Using light to control quantum materials in free space and optical cavities

The properties of complex quantum materials (QM), such as transition metal oxides, arise from the interplay of electrons, phonons, and magnons, making them highly sensitive to external parameters like pressure, doping, applDanierleied fields, and temperature. This susceptibility makes QM ideal for experiments where tailored electromagnetic fields can be used to induce novel properties on ultrafast timescales.
I will present our efforts to manipulate material properties through light, both in free space and optical cavities. I will start by discussing recent evidence of coherent control of dark states and address the thermodynamics of low dimensional magnetic systems. Building on our recent demonstration that a metal–insulator transition in 1T-TaS₂ can be controlled by resonant cavity coupling, I will outline our current research direction to control high temperature superconductors and sustain by cavity electrodynamics quantum coherence in condition where it is thermodynamically inhibited in free space.
