Spin dynamics with materials, atoms, and quantum computers: from Heisenberg chains at infinite temperature to emergent gauge fields on the triangular lattice
Spin dynamics with materials, atoms, and quantum computers: from Heisenberg chains at infinite temperature to emergent gauge fields on the triangular lattice
Refreshments will be provided before the talks at 3:45pm
Event Information:
Welcome to the fourth talk in our new Pioneers in Theoretical Physics Colloqium Series.
On February 25th, we present Dr. Joel Moore, the Chern-Simons Professor of Physics at the University of California, Berkeley, and Senior Faculty Scientist, Lawrence Berkeley National Laboratory.
Abstract:
One of the first nontrivial examples of quantum matter to be understood at equilibrium was the behavior of a chain of two-state spins, or qubits, entangled by nearest-neighbor interactions. Hans Bethe’s solution of the ground state in 1931 eventually led to the concept of Yang-Baxter integrability, and the thermodynamics were fully understood in the 1970s. However, the dynamical properties of this spin chain at any nonzero temperature remained perplexing until some unexpected theoretical and experimental progress beginning around 2019. Atomic emulators and quantum computers are beginning to complement solid-state quantum magnetism experiments, and computer scientists, physicists, and mathematicians all have their own reasons to care about the dynamics of simple arrangements of quantum spins. The last part of the talk covers how dynamics of more complicated spin models in higher dimensions are being used to search for emergent gauge fields in quantum matter.
Bio:
Joel Moore received his Ph.D. from MIT in 2001 and joined UC Berkeley and LBNL in 2002 after a postdoc at Bell Labs Lucent Technologies. He was promoted to tenure in 2007 and is currently the Chern-Simons Professor of Mathematical Physics. His work is primarily on the theory of correlated and topological states of electrons in solids, with applications to their transport, optical, and quantum coherent properties. Areas of his scientific contributions include the theory of topological phases and their electromagnetic responses, the role of quantum entanglement in understanding quantum matter analytically and computationally, and the nature of coherent quantum dynamics in many-body systems. He has been an NSF CAREER and Fulbright grantee and is an elected Member of the NAS, a Fellow of the APS, and a Simons Investigator. He has more than 150 scientific publications with a total of more than 20,000 citations, including a recent book on topological phases of matter co-authored with Roderich Moessner. He is former chair of the science advisory board for the Kavli Institute for Theoretical Physics and has chaired or co-chaired reports for the Department of Energy and National Science Foundation.
