The controlled manipulation of quantum materials with electromagnetic fields offers routes to states of matter that are inaccessible under equilibrium conditions. In this talk, I will discuss developments toward this goal, from nonthermal pathways and Floquet engineering with coherent light [1] to the control of quantum materials through coupling to quantized electromagnetic fields in optical...

Light–matter interactions enable out-of-equilibrium and equilibrium states in quantum solids and can give rise to new correlated phases. I will present our recent work on intralayer moiré excitons in twisted TMD systems. Using Bethe–Salpeter calculations based on a continuum electronic-structure model, we show that Coulomb exchange strongly influences these excitons, and that valley...

Prof. Zhiyuan Sun (University of Science and Technology of China)
The ponderomotive force is an effective static force that a particle feels in an oscillating field. We generalize this notion to the static force felt by the collective degrees of freedom in periodically driven quantum many-body systems [PRB 110, 104301 (2024)]. It may be used to predict their non-equilibrium steady states. We show that the ponderomotive force from the uniform incident light...
