Quantum materials change their properties when they interact with light. Optical cavities, for example, allow the electrical conductivity of quantum materials to be manipulated in a targeted manner. Physicists at FAU are investigating this enormous potential for electronics, energy storage and quantum computing.

When materials are forced to interact with light, their properties can change fundamentally. In a study, researchers at FAU and the University of Trieste demonstrated that tantalum sulfide, a metallic quantum material, can be switched from an electrical conductor to an insulator in optical cavities.
