Speaker: David Weld of UCSB Location: Bloomberg 462 Title: Probing quantum dynamics with strongly driven ultracold atoms Abstract: Degenerate gases in modulated optical potentials are a flexible testbed for the experimental study of quantum matter driven far from equilibrium. I will present results from a sequence of recent experiments in this area, on topics ranging from […]

Speaker: Mark Rudner (U Washington) “Dynamical quantum materials” When pushed out of equilibrium, quantum materials can host interesting types of internal fields -- dc or ac electric fields, currents, etc., -- that cannot persist in equilibrium. Feedback of these potentially very strong fields on the material's underlying band structure and quantum geometry can lead to […]

Speaker: Tomoya Higo of U. Tokyo Title: Electrical manipulation and detection of topological states in heterostructures based on the Weyl antiferromagnet Mn3Sn Abstract: Various elementary particles previously proposed in high-energy physics are now being observed as quasiparticles in solids, garnering significant attention. Recently, the existence of Weyl fermions/Weyl semimetal states, stemming from the macroscopic time-reversal […]

Speaker: William D. Ratcliff of NIST Title:  "Applications of Artificial Intelligence to Neutron Scattering” Abstract:  Neutron scattering is a versatile technique for studying the structure and dynamics of materials. Unfortunately, there are a limited number of neutron sources available in the world to perform scientific experiments. In this talk, I will discuss the use of […]
