Explore quantum many-body states and their control in solid-state systems through this 46-minute conference talk delivered by Atac Imamoglu from ETH Zurich at the Kavli Institute for Theoretical Physics. Delve into the fascinating world of controlling quantum states using short strong classical laser pulses, with particular focus on the optical control of Chern number in moire materials. Learn about recent developments in time-resolved experiments on solid-state systems, including the enhancement of correlated electron states, superconducting phases, magnetic properties, and topological states of matter. Gain insights into the intersection of quantum optics and materials science, understanding how cavity fields and quantum optical techniques can be applied to prepare, manipulate, and study correlated electron phases. Part of a broader conference bringing together theoretical and experimental researchers from solid state and quantum optics backgrounds to explore new directions in the field.
