D06 – Entangling collective behavior of quantum materials and quantum light
Condensed matter systems provide a paradigm platform for collective quantum behavior, where intriguing states of matter arise from the interaction between a macroscopic number of degrees of freedom. In this theory project, we aim to develop a microscopic theoretical framework, based on using non-equilibrium Green’s functions and quantum embedding theories, to explore the intriguing possibilities which arise when macroscopic properties of materials are controlled by the quantum electromagnetic field and vice versa. In exploring this direction, project D06 will merge ideas of quantum optics with the rapidly evolving field of classical light-induced phenomena in solids.
