SYUE: Symposium Ultrafast Excitation Pathways of Quantum Materials

SYUE 1: Ultrafast Excitation Pathways of Quantum Materials

Wednesday, March 29, 2023, 09:30–12:45, HSZ 01

Ultrafast laser experiments provide avenues to utilizing ultrafast light-matter interaction to control macroscopic properties of quantum materials. While conventional photo-induced processes in condensed matter often rely on ultrafast laser heating, there are intriguing pathways towards emergent macroscopic properties in quantum materials that are inherently non-thermal in nature. The mechanisms behind such pathways include transient modifications of the free-energy landscape by population redistributions, the dynamical modification of coupling strengths, and coherent light-matter dressing via Floquet engineering. This symposium brings together leading researchers in the field to showcase experimental and theoretical progress and discuss new avenues.
