SUMMARY:Sabrina Leslie: Single-molecule microscopy of RNA-lipid-nanoparticles: Bringing the nanoscale physics to help advance nanomedicines
DESCRIPTION:Sabrina Leslie: Associate Professor\, UBC Department of Physics and Astronomy and Michael Smith Labs \nAffiliate Faculty member\, SBME\, GSAT\, BIONF \nAbstract: I will present a unique quantitative single-particle imaging platform called CLiC (Convex Lens-induced Confinement) which enables simultaneous measurements of the size\, mRNA-payload\, and dynamic properties of vaccine and other nanoparticles in controlled\, cell-like conditions (Kamanzi et al\, ACS Nano 2021). Recently relocated to UBC PHAS and MSL from McGill in 2021\, our nanoparticle imaging team innovates nanoscale devices and approaches to investigate the structure-activity relationships which can help characterize and understand emerging classes of mRNA-lipid-nanoparticles such as COVID19 vaccines. We image individual confined\, freely diffusing particles in solution as well as during reagent-exchange\, such as in response to a change in solution pH\, in order to emulate/explore intracellular dynamics in a controlled setting. Over the long term and in collaboration with health/therapeutic scientists\, we are working towards correlating detailed multi-scale data sets\, including single-particle measurements made in vitro as well as in cells and tissues\, with clinical results\, to create a through-line of understanding of vaccine/drug effectiveness from the microscopic to clinical scale. Our inspiration is to innovate and use nanoscale tools to obtain new biophysical insights into how and why medicines work to enable and optimize their rational design and engineering. This talk builds off our recent publication in ACS Nano (Kamanzi et al\, 2021)\, describes our ongoing collaboration with the Cullis laboratory and others (UBC Health Sciences)\, and shares an outlook including opportunities for new PHAS and interdisciplinary graduate students at UBC looking to join an exciting interdisciplinary team of biophysicists. The Leslie Lab has recently set up its new laboratory at MSL/NCE with several state-of-the-art microscopes and we are excited to share our work with QMI and get to know our new community through and after this seminar. \n \nCaption: CLiC single-particle imaging and analysis of Lipid Nanoparticles (LNPs) enables characterization of detailed size and loading distributions of RNA–LNP complexes. A) Compressing the flow-cell confines LNPs for extended study. B) Trapped LNPs are shown in microwells. 100s – 1000s of isolated LNPs are imaged in parallel\, a process which can be repeated thousands of times. C) Single-particle tracking is used to obtain LNP trajectories\, which are then used to obtain particle diffusivity/ size (D) as well as intensity/RNA payload (E). This information is then used to define LNP size and RNA payload distributions and inform structure-activity relationships of the nanoparticles in conjunction with other dynamic\, multi-scale and biological data.

SUMMARY:Dr. Guosong Hong: Seeing the Sound: Optical and Ultrasonic Brain Interfaces Based on Materials Advances
DESCRIPTION:Dr. Guosong Hong – Stanford University  \nTitle: Seeing the Sound: Optical and Ultrasonic Brain Interfaces Based on Materials Advances \nAbstract: Today’s optical neuromodulation and imaging methods enable causal manipulation of neural activity to dissect complex circuit connections underlying certain behaviors and facilitate brain-computer interfaces. In these approaches\, visible light is commonly used\, thus limiting penetration depth in vivo and necessitating an invasive procedure that damages the endogenous brain tissue and constrains the subject’s free behavior. In this talk\, I will present three recently developed methods to address these challenges based on novel material advances: sono-optogenetics\, infrared optogenetics\, and an intravascular light source. In sono-optogenetics\, we demonstrate that mechanoluminescent materials can convert focused ultrasound into localized light emission for noninvasive optogenetic neuromodulation in live mice. In addition\, inspired by the infrared sensitivity of rattlesnakes\, we developed an approach to use brain-penetrant infrared light for tether-free and implant-free neuromodulation throughout the entire brain in freely behaving mice. Lastly\, we leveraged a biomineral-inspired approach to synthesize nanoscopic phosphors as an intravascular light source. In contrast to conventional external light sources\, this intravascular light source offers deeper tissue penetration for imaging the mouse brain through the uncleared skull. I will conclude my talk by presenting an outlook on how advances in condensed matter may facilitate our understanding of the mind. \nBiography: Dr. Guosong Hong received his Ph.D. in chemistry from Stanford University in 2014 and then carried out postdoctoral studies with at Harvard University. Dr. Hong joined Stanford Materials Science and Engineering and Neurosciences Institute as an assistant professor in September 2018. His research at Stanford aims to develop and apply novel optical and electronic materials for minimally invasive brain interfacing. He is a recipient of the NIH Pathway to Independence (K99/R00) Award\, the MIT Technology Review ‘35 Innovators Under 35’ Award\, the Science PINS Prize for Neuromodulation\, the NSF CAREER Award\, the Walter J. Gores Award for Excellence in Teaching\, and the Rita Allen Foundation Scholars Award.

SUMMARY:CM Seminar: Dr. Tina Rost\, High Entropy Ceramics: Investigating localized structural effects on emerging properties
DESCRIPTION:Speaker: Dr. Tina Rost \nDate: Thursday September 29 2022 \nTime: 10:00 am – 11:00 AM PST \nLocation: Zoom \nZoom Link: https://ubc.zoom.us/j/64243489212?pwd=YkFSMDdxN3Nhbm15aExBdTF6MnBvQT09 \nMeeting ID: 642 4348 9212 \nPasscode: 742838 \n  \nAbstract\nMany properties we observe in materials are a direct consequence of their composition and local structure. High entropy materials are a unique class of systems that do not have a primary composition; rather they contain a near-equimolar distribution of several elements— where no single element serves as host. Such compositional disorder is accompanied by a unique distribution of localized structural distortions that can have a profound effect on properties such as thermal conductivity\, magnetic interaction\, diffusion\, and more. To date\, high entropy metals and ceramics are gaining significant traction in the materials community as unique and interesting properties continue to emerge\, from amorphous-like thermal conductivities to exotic magnetic states. In this talk\, we present and discuss ongoing work on the local characterization of several high entropy compositions exhibiting crystal structures from rocksalts to Kagome lattices. In particular\, the use of X-ray absorption fine structure (XAFS) is demonstrated to aid in understanding such disorder on the local level and how it may influence functional properties \n  \nSpeaker Bio\nDr. Christina Rost is currently an Assistant Professor of Physics at James Madison University in Harrisonburg\, VA. She graduated with a Ph.D. in Materials Science and Engineering from North Carolina State University in 2016\, following both a B.S. and an M.S. in Physics from Indiana University of Pennsylvania. Her Ph.D. focused on the development and phase-characterization of a novel class of oxide systems stabilized through configurational disorder\, named “Entropy Stabilized Oxides”.   After graduation\, Tina was Postdoctoral Research Associate in the Experiments and Simulations in Thermal Engineering (ExSITE) group\, within the Department of Mechanical and Aerospace Engineering at the University of Virginia. There\, her work focused on experimental methods to test thermal properties at extremely high temperatures and thermal transport in complex and high-entropy oxides and carbides. Currently\, her all-undergraduate research group at JMU focuses efforts on complex oxide synthesis and characterization. She is an active member of the American Ceramics Society and the American Physical Society.

SUMMARY:Dr. Sebastian Paeckel: Tensor network methods for open electron-phonon systems: Bipolarons in the presence of dissipation
DESCRIPTION:Dr. Sebastian Paeckel: Dr. Sebastian Paeckel is from LMU Germany and is one of the world leading experts in Tensor Network methods. \nTitle: Tensor network methods for open electron-phonon systems: Bipolarons in the presence of dissipation \nAbstract: Studying the interplay between electrons and phonons recently has seen a remarkable revival\, driven by both methodical progress\, as well as fascinating new physical insights\, such as the possibility of light-bipolaron induced superconductivity [1\,2] or the enhancement of transport properties [3]. Here\, investigating the effects of environments (dissipative\, thermal\, driven) coupled to the phonon system is a crucial but enormously challenging problem\, which on the one hand is important to understand the validity of effective\, isolated models\, while on the other hand allows for tailored manipulations of the phononic state. Recently\, we developed a new toolbox of tensor network methods which are designed to allow an efficient treatment of electron-phonon systems in- and out-of equilibrium as well as coupled to an environment. Exhibiting a speed-up of significantly more than an order of magnitude\, we are able to implement open quantum system techniques\, which previously had been way too expensive to be of proper use for studying large system sizes by means of tensor network methods.\nIn this talk I introduce the developed tools and give a brief overview of the current state\, their potential and limitations. Furthermore\, I discuss a first application\, namely the effect of a dissipative environment\, coupled to the Hubbard-Holstein model\, putting the emphasis on a previously reported enhancement of the metallic phase.\n[1]  Phys. Rev. Lett. 121\, 247001 (2021)\n[2]  https://doi.org/10.48550/arXiv.2203.07380\n[3] Scientific Reports volume 7\, 3774 (2017) \nShort Bio: Sebastian did his PhD in Göttingen from 2015-2019 focussing on the development Matrix Product States (MPS) methods\, in particular time evolution methods. In 2019 he had an internship at Microsoft Station Q iand studied transport through Majorana Islands. In 2020\, he became a Junior Researcher Leader in LMU in Munich and started studying electron phonon systems (method development and application\, also to quantum chemistry problems).

Jason Jones – University of Arizona \nTitle: Frequency Comb Spectroscopy of Laser Produced Plasmas \nWhen: Wednesday\, October 12\, 2022 at 11am \nWhere: QMI 488 \nAbstract: In this talk I’ll give an overview of our work developing spectroscopic techniques with frequency comb sources from the XUV to the MIR. In particular\, I’ll focus on our work studying basic aspects of atomic\, ionic\, and molecular formation in laser-produced plasmas (LPP’s) using dual-comb spectroscopy. Our interest in such LPP’s includes their use in sample preparation for precision atomic/molecular spectroscopy and material analysis as well as surrogates for studying chemical/nuclear explosions and formation of heavy elements within kilonova. \nBio: Professor R. Jason Jones holds the John Paul Schaefer Endowed Chair in Optical Sciences at the University of Arizona. He leads a research group in experimental optical physics at the Wyant College of Optical Sciences. His research interests include ultrafast optics\, nonlinear light-matter interactions\, high-precision optical spectroscopy\, and the development and application of femtosecond frequency combs. Recent work focuses on novel architectures for optical atomic clocks and time-resolved dual-comb spectroscopy from the XUV to the MIR\, including the first demonstration of its use in studying atomic\, ionic\, and molecular formation inside laser-produced plasmas. Dr. Jones has also been instrumental in the establishment of the annual Winter School and Workshop at the Wyant College of Optical Sciences as a nation-wide event to introduce undergraduates to research and career opportunities in the field of Optics and Photonics. Dr. Jones received his PhD from the University of New Mexico in 2001. He continued his work as a research associate at JILA (a joint institute of the University of Colorado and the National Institute of Standards and Technology)\, where he was supported by a fellowship from the National Research Council\, working on the continued development and applications of fs frequency combs. In 2005 he demonstrated the up-conversion of frequency combs into the vacuum-ultraviolet for the first time. He continued to work as a Senior Research Associate of JILA until July 2006 when he left to join the College of Optical Sciences at the University of Arizona. He is a recipient of the NSF CAREER award and DARPA’s Young Investigator awards and is a member of the American Physical Society and the Optical Society of America. He holds two US patents and has published over 50 peer-reviewed articles.

SUMMARY:CM Seminar: Dr. Anushya Chandran - Quantization of Dynamics in Quasi-periodically Driven Systems
DESCRIPTION:Dr. Anushya Chandran: Boston University \nTitle: Quantization of dynamics in quasi-periodically driven systems \nAbstract: In the past decade\, quantum simulators have increased in their power and scope\, offering exquisite dynamical control of tens or even hundreds of individual atoms/ions. \nConcurrently\, a topological revolution in our understanding of electronic band structures has taken place\, driven by the discovery of topological insulators\, graphene and other topological materials. Remarkably\, these advances can be connected — the dynamics of driven few level systems can be described using band structures in “synthetic dimensions\,” one per driving tone. Topological order in the synthetic band structure then leads to quantized dynamical responses in the quantum simulator. \nIn this talk\, I will use a unifying frequency lattice construction to reveal non-adiabatic topological responses in quasi-periodically driven systems. We will find that quasi-periodically driven qubits already exhibit topologically distinct dynamical phases\, and that a 2-tone driven wire can function as a quantized energy pump at any temperature. The latter system provides one of the few examples of many-body localization protected order that is absolutely stable. I will argue that the quantized energy pumping regime is accessible in near-term optical and microwave cavity-QED experiments\, and that furthermore\, it is useful to prepare highly excited non-classical cavity states and entangled cavity-qubit states. \nBio: Anushya Chandran studies the organizing principles of quantum systems far from equilibrium. Her research sheds light on the process of thermalization\, designs protocols to achieve non-trivial quantum dynamics\, and informs near-term quantum device design. Anushya hails from India\, where she studied at the Indian Institute of Technology in Madras. She received her PhD from Princeton University and performed post-doctoral research at Perimeter Institute before joining Boston University. She is the recipient of the Sloan fellowship and the NSF young investigator career award. \n

SUMMARY:CM Seminar: Zac Ward - Disorder as an Order Parameter
DESCRIPTION:Zac Ward – Oak Ridge National Laboratory \nTitel: Disorder as an Order Parameter \nAbstract: The way that materials behave can simply be thought of as a response to what the electrons in the material are doing. Controlling the atoms’ arrangement to one another in a crystal lattice changes where the electrons reside and how they interact with one another. If we can continuously control atomic compositions and structural relationships between the constituent elements\, we can then manipulate functionality with unprecedented precision. In this presentation\, I will describe our efforts to open previously inaccessible lattice symmetries and compositional phase spaces in strongly correlated quantum materials by means of light ion implantation and entropy-assisted synthesis. I will provide examples from our recent works that demonstrates how continuous control of symmetry opens new avenues to manipulate magnetic anisotropy and how compositional complexity can be used to design dynamic spin frustration by tailoring local degeneracies. We will close with a discussion of how shifting local variances in spin and exchange coupling types while maintaining position symmetries provides exciting opportunities for designing novel Griffiths phases or quantum many-body systems with tunable critical behaviors. \nBio: Zac Ward is a Senior Scientist in the Quantum Heterostructures Group at Oak Ridge National Laboratory. His research is directed at understanding and controlling electronic interactions in novel materials aimed at identifying transformative information and energy technologies of pressing economic and environmental need. Underpinning this effort is expertise in 1) single crystal film synthesis using pulsed laser deposition and light element ion implantation to tailor spin\, charge\, and orbital degrees of freedom; and 2) structural and functional characterization using labscale x-ray diffraction\, magnetometry\, transport characterization\, and beamline-based x-ray spectroscopy and neutron reflectometry. \n

SUMMARY:CM Seminar: Professor Romain Vasseur - Anomalous Diffusion in Quantum Spin Chains
DESCRIPTION:Professor Romain Vasseur – University of Massachusetts\, Amherst \nTitle: Anomalous diffusion in quantum spin chains  \nAbstract: High-temperature quantum transport is usually assumed to be incoherent and diffusive.  In this talk\, I will explain how anomalous transport in quantum spin chains can emerge from proximity to special integrable limits\, due to a hierarchy of long-lived quasiparticle excitations. I will summarize our understanding of finite-temperature transport in integrable spin chains\, and argue that integrability-breaking perturbations can generically lead to either super- or subdiffusion up to very long-time scales. \nBio: Romain Vasseur is an Associate Professor in the Physics Department of the University of Massachusetts\, Amherst.  He is a condensed matter theorist working on strongly correlated quantum systems and quantum information\, with a focus on the interplay of strong interactions and quantum entanglement\, leading to new emergent phenomena both in thermal equilibrium and in non-equilibrium quantum systems. Before moving to Amherst\, Dr. Vasseur was a Postdoctoral Fellow at Lawrence Berkeley National laboratory (2013-2017)\, working in the Condensed Matter Theory Center at the University of California\, Berkeley. He obtained his PhD at IPhT (CEA\, Saclay) and LPTENS (ENS\, Paris) in 2013. Prof. Vasseur has been recognized as a fellow of the Alfred P. Sloan Foundation (2019) and an Early Career Award of the US Department of Energy (2018). He is also the recipient of a Young Investigator Award of the US Air Force Office of Scientific Research (2020). \n

SUMMARY:CM Seminar: Long Ju - Electron Correlation and Coupling with Phonon in the Trilayer Graphene/hBN Moire Superlattice
DESCRIPTION:Long Ju – MIT Physics Department  \nTitle: Electron Correlation and Coupling with Phonon in the Trilayer Graphene/hBN Moire Superlattice \nAbstract: ABC-stacked trilayer graphene/hexagonal boron nitride moiré superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. A spectroscopy study of this system is\, however\, challenging due to the device configuration. In this talk\, I will introduce our recent efforts on FTIR photocurrent spectroscopy measurements of dual-gated TLG/hBN. We observed strong gate-tunable optical transitions that originated from the moire flat band. At half-filling of the valence flat band\, a broad absorption peak emerges at ~18 meV\, indicating direct optical excitation across an emerging Mott gap. Furthermore\, I will talk about a unique moire-enabled interlayer electron-phonon coupling phenomenon in this system. The ZO phonon in hBN hybridizes with electron-hole excitations in trilayer graphene and appear as an asymmetric peak in the photocurrent spectrum. This Fano line-shaped peak evolves continuously as we tune the displacement field. I’ll talk about the implications of this phenomenon to engineering the physics of moire quantum matters. \nBio: Long Ju joined the MIT Physics Department as an assistant professor in January 2019. He received his B.S. in Physics in 2009 from Tsinghua University\, China\, and his Ph.D. in Physics in 2015 from the University of California\, Berkeley. He then moved to Cornell University\, where he was a Kavli postdoctoral fellow until December 2018. \n  \n​ \n

SUMMARY:CM Seminar: Thomas Scaffidi - Spread and Erase - How Electron Hydrodynamics Can Eliminate the Landauer-Sharvin Resistance
DESCRIPTION:Thomas Scaffidi – University of California Irvine \nTitle: Spread and Erase – How Electron Hydrodynamics Can Eliminate the Landauer-Sharvin Resistance \nAbstract: What is the ultimate limit of conductance of a metallic device of lateral size W? In the ballistic limit\, the answer is the Landauer-Sharvin conductance\, which is associated with an abrupt reduction of the number of conducting channels when going from the contacts to the device. However\, the ballistic limit is not always the best-case scenario\, since adding strong electron-electron scattering can take electrons to a viscous regime of transport for which “super-ballistic” flows were recently studied. In this talk\, we will show that by a proper choice of geometry which resembles a “wormhole”\, it is possible to spread the Landauer-Sharvin resistance throughout the bulk of the system\, allowing its complete elimination by electron hydrodynamics. This effect arises due to the interplay between geometry and strong electron-electron scattering\, which allows for a net transfer of carriers from reflected to transmitted channels. Finally\, we will discuss a recent experiment in a Corbino geometry which realizes one half of this “wormhole” geometry. \nRefs:\nTheory: Phys. Rev.

SUMMARY:CM Seminar: Mark Rudner: “The Lindblad Quantum Master Equation: Not Just for quantum Optics Anymore"
DESCRIPTION:Prof. Mark Rudner – University of Washington \nTitle: “The Lindblad Quantum Master Equation: Not Just for quantum Optics Anymore” \nAbstract: With the exception of the universe as a whole\, the evolution of a quantum system is generically non-unitary due to the coupling between the system and its environment. In quantum optics\, the powerful framework of Lindblad master equations has been developed and employed for many years to describe the effective evolution of atomic-like systems in the presence of electromagnetic and other environmental degrees of freedom. Importantly\, explicit derivations of Lindblad master equations have traditionally relied on highly restrictive assumptions on energy level spacings that limit its applicability to few-level/few-body systems. In this talk I will review the basic features of evolution of open quantum systems\, and describe a new route to obtaining the Lindblad equation which circumvents all restrictive assumptions on the nature of the system at hand. This “universal Lindblad equation” can therefore be applied to a wide range of many-body systems\, including emerging quantum hardware with several to many coupled qubits and many-body systems driven far from equilibrium. The explicit expressions for the “jump operators” that describe incoherent processes induced by the bath have a natural interpretation in terms of an operator spreading picture\, akin to that which has recently provided much insight into thermalization of closed quantum systems. I will conclude with a discussion of future prospects and applications of this new framework. \nBio: Mark Rudner is the Kenneth K. Young Memorial Professor of Physics at the University of Washington. His research interests span a broad range of topics in theoretical condensed matter physics and quantum dynamics. Following his PhD at MIT\, in which he studied classical and quantum control in solid state spin and superconducting qubits\, as well as transport in graphene\, in 2008 Mark moved to Harvard for a postdoctoral fellowship. During this time\, he developed foundational works on topological phenomena in both driven (“Floquet”) and open (non-Hermitian) quantum systems. In 2012\, Mark moved to Copenhagen\, where he joined the Center for Quantum Devices at the Niels Bohr Institute and took charge of the Condensed Matter Theory group at the Niels Bohr International Academy. Over the next decade\, Mark maintained a role as one of the leaders in the emerging fields of Floquet engineering and non-equilibrium quantum dynamics\, while further exploring novel (linear and non-linear) collective phenomena that arise from the interplay of quantum geometry and interparticle interactions. In 2021 Mark joined the University of Washington\, where he is continuing these efforts while expanding into new directions in collaboration with his experimental and theoretical colleagues.

SUMMARY:Special Seminar by Kyle Monkman - Symmetry Protection in Hermitian and Non-Hermitian Hamiltonians 
DESCRIPTION:Speaker: Kyle Monkman\, The University of Manitoba \nTalk title: Symmetry Protection in Hermitian and Non-Hermitian Hamiltonians  \nAbstract: Symmetry-protected topological insulators are protected by both the symmetry and by the system’s band gap. This protection means that certain properties of the system remain unchanged by deformations of the (Hermitian) Hamiltonian. In my PhD work\, we have shown that entanglement is a symmetry protected quantity in various symmetry classes. \nOn the other hand\, when considering a system in an external environment\, it is difficult to show that the system is topologically protected. It is in these cases that modelling the time dynamics with a non-Hermitian Hamiltonian becomes relevant. Ultimately\, the goal is to classify non-Hermitian time dynamics under various symmetry constraints. If measurable quantities are protected in these systems\, then we would have a very robust quantum state.

SUMMARY:CM Seminar: Alannah Hallas: Entropy Engineering and Tunable Magnetic Order in the Spinel High Entropy Oxide
DESCRIPTION:Dr. Alannah Hallas: Blusson Quantum Matter Institute \nTitle: Entropy engineering and tunable magnetic order in the spinel high entropy oxide \nAbstract: The field of high entropy oxides (HEOs) flips traditional materials science paradigms on their head by seeking to understand what properties arise in the presence of profound configurational disorder. This disorder\, which emerges as the result of multiple elements sharing a single crystalline lattice\, can take on a kaleidoscopic character due to the vast numbers of possible elemental combinations and appears to imbue some HEOs with functional properties that far surpass their conventional analogs. While experimental discoveries abound\, efforts to characterize the true magnitude of the configurational entropy and understand its role in stabilizing new phases and generating superior functional properties have lagged behind. Understanding the role of configurational disorder in existing HEOs is the crucial link to unlocking the rational design of new HEOs with targeted properties. In this talk\, I will discuss our group’s efforts to establish a framework for articulating and beginning to address these questions towards achieving a complete understanding of the true role of entropy in HEOs. \nBio: Alannah Hallas is an Assistant Professor in the Department of Physics & Astronomy at UBC\, a Principal Investigator at the Stewart Blusson Quantum Matter Institute\, and a CIFAR Azrieli Global Scholar in Quantum Materials. Alannah’s research program is focused on the design\, discovery\, and crystal growth of new quantum materials\, leveraging a wide range of advanced crystal growth techniques. Her group characterizes the quantum magnetic properties of their materials using x-ray and neutron scattering as well as muon spin relaxation techniques.

SUMMARY:CM Seminar: Patrick Ledwith – Harvard  University: Vortexability Chern bands in Twisted and Strained Graphene
DESCRIPTION:Patrick Ledwith – Harvard University \nTitle: Vortexability Chern bands in Twisted and Strained Graphene \nAbstract: Fractional Chern insulators realize the remarkable physics of the fractional quantum Hall effect (FQHE) in crystalline systems with Chern bands. The lowest Landau level (LLL) is known to host the FQHE\, but not all Chern bands are suitable for realizing fractional Chern insulators (FCI). Previous approaches to stabilizing FCIs focused on mimicking the LLL through momentum space criteria. Here instead we take a real-space perspective by introducing the notion of vortexability. Vortexable Chern bands admit a fixed operator that introduces vortices into any band wavefunction while keeping the state entirely within the same band. Vortexable bands admit trial wavefunctions for FCI states\, akin to Laughlin states. In the absence of dispersion and for sufficiently short ranged interactions\, these FCI states are the ground state — independent of the distribution of Berry curvature. Vortexable Chern bands were found to emerge naturally in chiral twisted graphene\, and fractional Chern insulators were subsequently observed experimentally. They were also recently proposed in periodically strained graphene. \nBio: Patrick Ledwith grew up near Philadelphia\, Pennsylvania. He got his undergraduate degree in Physics and Mathematics at MIT. There he worked with Leonid Levitov on electron hydrodynamics\, discovering and elucidating long-lived collective excitations in two-dimensional electron gases. He is now a graduate student working in Ashvin Vishwanath’s group. Here he has worked on several aspects of moiré materials including fractional Chern insulators\, superconductivity\, correlated insulators\, and topological charge density waves. He has been especially interested in developing analytic approaches to fractional Chern insulators. He has applied these methods to twisted bilayer graphene where they work especially well. He subsequently partnered with Amir Yacoby’s group in realizing and understanding experimentally observed fractional Chern insulating states at small magnetic fields. In his free time\, he likes to cook and play video games with his dog.

SUMMARY:CM Seminar: John Birkbeck – Weizmann Institute of Science: The Quantum Twisting Microscope
DESCRIPTION:John Birkbeck – Department of Condensed Matter Physics\, Weizmann Institute of Science.\nTitle: The Quantum Twisting Microscope\n \nAbstract: In this talk\, I will present a new type of scanning probe microscope\, the Quantum Twisting Microscope (QTM)\, capable of performing local quantum interference measurements at a twistable interface between two quantum materials. Its working principle is based on a unique tip made of an atomically-thin two-dimensional material. This tip allows electrons to coherently tunnel into a sample at many locations at once\, with quantum interference between these tunneling events\, making it a scanning electronic interferometer. With an extra twist degree of freedom\, our microscope becomes a momentum-resolving local probe\, providing powerful new ways to study the energy dispersions of interacting electrons. I will present various experiments performed with this microscope\, demonstrating quantum interference at room temperature\, probing the conductance of in-situ twisting interfaces\, and imaging local energy dispersions of graphene and twisted bilayer graphene. \nSpeaker Bio: I am a postdoctoral researcher working at the Weizmann Institute of Science with Prof. Shahal Ilani. I completed my Ph.D. with Prof. Andre Geim and Prof. Irina Grigorieva at the University of Manchester\, UK. My research focuses on using unique scanning probe microscopes to visualize the electronic properties of 2D materials and vdW heterostructures.

SUMMARY:CM Seminar: Frédéric Grillot – Télécom Paris/ University of New-Mexico: Semiconductor Quantum Dots
DESCRIPTION:Frédéric Grillot – Télécom Paris/ University of New-Mexico\nTitle: Semiconductor Quantum Dots \nAbstract: Semiconductor nanostructures with low dimensionality like quantum dots are one the best attractive solutions for achieving high performance photonic devices. When one or more spatial dimensions of the nanocrystal approach the de Broglie wavelength\, nanoscale size effects create a spatial quantization of carriers along with various other phenomena based on quantum mechanics. Thanks to their compactness\, great thermal stability and large reflection immunity\, semiconductor quantum dot lasers are very promising candidates for low energy consumption and isolation free photonic integrated circuits. When directly grown on silicon\, they even show a four-wave mixing efficiency much superior compared to the conventional quantum well devices. This remarkable result paves the way for achieving high-efficiency frequency comb generation from a photonic chip. Quantum dot lasers also exhibit a strong potential for applications in optical routing and optical atomic clock. Last but not least\, a quantum dot single photon source is a building block in secure communications\, and therefore can be applied to quantum information processing for applications such as quantum computers.

SUMMARY:CM Seminar: Xie Chen – California Institute of Technology:  Fracton and Chern-Simons Theory
DESCRIPTION:Xie Chen – California Institute of Technology\nTitle: Fracton and Chern-Simons Theory \nAbstract: Fracton order describes the peculiar phenomena that point excitations in certain strongly interacting systems either cannot move at all or can only move in a lower dimensional sub-manifold. It has recently been discovered in various lattice models\, tensor gauge theories\, etc. In this talk\, we discuss how another powerful field theory framework — the 2+1D Chern-Simons (CS) gauge theory — can be used to provide new insight and explore new possibilities in 3+1D fracton order. 2+1D U(1) gauge theories with a CS term provide a simple and complete characterization of 2+1D Abelian topological orders. To study 3+1D fracton order\, we extend the theory by taking the number of component gauge fields to be infinity. In the simplest case of infinite-component CS gauge theory\, different components do not couple to each other and the theory describes a decoupled stack of 2+1D fractional Quantum Hall systems with quasi-particles moving only in 2D planes — hence a fractonic system. More interestingly\, we find that when the component gauge fields do couple through the CS term\, more varieties of fractonic orders are possible. For example\, they may describe foliated fractonic systems which extends the framework found in exactly solvable models. Moreover\, we find examples which lie beyond the foliation framework\, characterized by 2D excitations of infinite order and braiding statistics that are not strictly local. \nSpeaker Bio: Xie Chen is a Professor of Theoretical Physics at the California Institute of Technology. Dr. Chen obtained her Ph.D. degree from MIT in 2012 and was a Miller research fellow at the University of California\, Berkeley before joining Caltech in 2014.

SUMMARY:CM Seminar: Leslie M. Schoop – Princeton University:  The Chemistry of Quantum Materials
DESCRIPTION:Leslie M. Schoop – Princeton University\nTitle:  The Chemistry of Quantum Materials  \nAbstract: Quantum materials are hoped to change technology in various aspects. However\, most of the desired applications are hindered by the lack of suitable materials. In my group we are using concepts from chemistry to understand\, predict and synthesize new quantum materials. In this talk\, I will show how simple concepts\, such as measuring bond distances\, allow us to make predictions about electronic structures of materials\, which we can then use to find new quantum materials. I will also show how we can use chemical exfoliation\, a synthesis method that is much more used in energy science to create 2D nanosheets\, to synthesize novel 2D quantum materials. Examples are 2D magnets and superconductors\, for which our synthesis method allows for large-scale productions of inks to print electronics. \nSpeaker Bio: Dr. Leslie M. Schoop received her Diploma in Chemistry from Johannes Gutenberg University (2010) and PhD in Chemistry from Princeton University (2015). She then went on to work as a Minerva fast-track fellow under Professor Bettina Lotsch at the Max Planck Institute for Solid State Research (2015-2017). Dr. Schoop joined the Princeton University Department of Chemistry Faculty in 2017 and was tenured in 2022. In 2019 she won the Beckman Young Investigator award and became a Moore foundation EPiQS Materials Synthesis Investigator. In 2020 she was awareded the Packard fellowship for science and engineering and in 2021 the Sloan fellowship in Chemistry and the DOD Office of Naval Research Young Investigator award. In 2022 you was awarded the NSF CAREER award. The Schoop Lab is working at the interface of chemistry and physics\, using chemical principles to find new materials with exotic physical properties. \n(This event is virtual and can be watched at the link below or in BRIM/AMPL 311)

SUMMARY:CM Seminar: Erik Sorensen – McMaster University: Ground State Solitons in Kitaev Spin Chains
DESCRIPTION:Erik Sorensen – McMaster University\nTitle: Ground State Solitons in Kitaev Spin Chains \nAbstract: The bond-dependent Ising interaction present in the Kitaev model has recently attracted considerable attention. The attention has mostly focused on the two-dimensional honeycomb lattice version of the Kitaev model where several materials has been identified as potential realizations. However\, one can also imagine realizing simpler one-dimensional Kitaev spin chains that still has a surprisingly rich structure. One example is the ferromagnetic material CoNb2O6 which shows signatures of bond dependent interactions.  It is usually assumed that for the Kitaev spin chains the presence of a magnetic field does not lead to any interesting new physics. However\, recently we have identified an unusual chiral soliton phase in antiferromagnetic Kitaev chains\, appearing when the field is applied in specific directions. The phase is centered around a special point where a two-fold degenerate ground-state can be exactly found. In this talk I will present some of the interesting physics related to the soliton phase for both integer and half-integer spin and discuss a simple variational\npicture of the soliton phase. \nSpeaker Bio: Erik Sorensen is originally from AArhus Denmark. He got his Ph. D. at the University of California\, Santa Cruz in Physics in 1992. After UCSC\, he spent two years (1992-94) as a postdoc at UBC in the physics department . From British Columbia he moved to Bloomington\, Indiana for a second postdoc (1994-96) in the condensed matter theory group. From December 1996 till the fall of 2001\, Professor Sorensen worked as a professeur at the Université Paul Sabatier in Toulouse and in the fall of 2001\, he joined the department of physics and astronomy at McMaster University. In general\, he work in the area of strongly correlated systems\, often on low-dimensional models of frustrated magnets and electronic and superconducting systems\, often using state of the art computational methods.
