Collective theory for an interacting solid in a single-mode cavity
Katharina Lenk, Jiajun Li, Philipp Werner +1
We investigate the control of interacting matter through strong coupling to a single electromagnetic mode, such as the photon mode in a Fabry-Perot or split-ring cavity. For this p…

Collective excitations of the U(1)-symmetric exciton insulator in a cavity
Katharina Lenk, Martin Eckstein
We investigate the equilibrium state and the collective modes of an excitonic insulator (EI) in a Fabry-Pérot cavity. In an EI, two bands of a semiconductor or semimetal spontaneou…
