DESCRIPTION:Titel: Non-equilibrium as a resource: Non-thermal steady-s
 tates of cavity-quantum-materials Abstract: Coupling a system to two d
 ifferent baths can lead to novel phenomena escaping the constraints of
  thermal equilibrium. In quantum materials inside optical cavities\, t
 his feature can be exploited as electrons and cavity-photons are easil
 y pulled away from their mutual equilibrium\, even in the steady state
 . This offers new routes for a non-invasive control of material proper
 ties and functionalities. Motivated by recent experimental puzzles ari
 sing with transition-metal-dichalcogenides inside Fabry-Perot cavities
 \, we show how the absence of thermal equilibrium between electrons an
 d photons leads to qualitative modifications of the material&#8217\;s 
 properties in two different ways: 1) the electron distribution shows e
 nhanced fluctuations near the Fermi surface due to the breaking of det
 ailed balance\; 2) the scattering between electrons in the steady stat
 e acquires a genuinely non-thermal component which can for instance en
 hance the tendency to pair and become superconducting. Sprecher / Spea
