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: Joyce Poon: Visible-light Silicon Integrated Photonics for Future Computing
DESCRIPTION:Joyce Poon – University of Toronto \nTitle: Visible-light Silicon Integrated Photonics for Future Computing \nAbstract: The emerging demands of computing require hardware advances to realize new types of computing architectures and interfaces. Foundry silicon photonics leverages the maturity of microelectronics manufacturing to fabricate photonic integrated circuits. Today\, silicon photonics is mostly used in the short-wave infrared spectrum for optical communications. I will discuss how foundry silicon photonics in the visible spectrum is an enabling technology for future computing\, addressing applications such as displays\, neural implants\, and quantum computing. \nBiography: Joyce Poon is the Managing Director at the Max Planck Institute of Microstructure Physics\, a Professor of Electrical and Computer Engineering at the University of Toronto\, and an Honorary Professor in the Faculty of Electrical Engineering and Computer Science at the Technical University of Berlin.  She currently serves as a Director-at-Large for Optica (formerly the Optical Society\, OSA). She and her team specialize in integrated photonics on silicon.  Prof. Poon obtained the Ph.D. in Electrical Engineering from Caltech in 2007. She is a Optica Fellow and a Fellow of the IEEE.

SUMMARY:CM Seminar: Professor Kai-Mei C Fu - Quantum Point Defects: Can These Defects Be Less Defective?
DESCRIPTION:Professor Kai-Mei C Fu –  University of Washington  \nTitle: Quantum point defects: Can these defects be less defective? \nAbstract: Point defects in crystals are the solid state analog to trapped ions. Thus these “quantum defects”\, which can be integrated into solid-state devices\, have gained popularity as qubit candidates for scalable quantum networks. In this talk\, I will introduce some of the basic quantum defect properties desirable for quantum network applications. I will highlight my own group’s efforts at understanding and controlling the properties of defects in diamond including (1) synthesis\, frequency and emission control of deep-level vacancy complexes in diamond and (2) properties of shallow-level donors in ZnO\, including single donors and intentionally synthesized donors in ZnO. \nBio: Kai-Mei Fu is the Virginia and Prentice Bloedel Professor of Physics and Electrical and Computer Engineering at the University of Washington and holds a dual appointment with the Pacific Northwest National Laboratory. Kai-Mei received their PhD in Applied Physics \nin 2007 from Stanford University. Their research focuses on the synthesis\, characterization and control of optically active quantum defects in crystals\, with applications in quantum networks and sensing. At UW\, Kai-Mei is the Director of UW’s NSF National Research Training Program: Accelerating Quantum-Enabled Technologies and the co-chair of UW’s interdisciplinary QuantumX Steering Committee.  They are also the Deputy Director of the Department of Energy National Quantum Initiative (NQI) Co-design Center for Quantum Advantage. In their free time\, Kai-Mei enjoys spending time with their family outdoors in the beautiful Pacific Northwest. \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
