The discovery of high-temperature superconductivity in bulk La3Ni2O7 under high hydrostatic pressure has ignited significant interest in understanding the interplay between atomic and electronic structure in these compounds.
A grand aspiration of cavity quantum materials research is to uncover fundamentally new routes for controlling properties of matter by judiciously tailoring the quantum electromagnetic environment. Experiments with dark cavities revealed modified transport properties in the integer and fractional quantum Hall states of a 2D electron gas, as well as cavity-assisted thermal control of the metal-to-insulator transition in charge-density-wave systems.
