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.
