Probing non-equilibrium steady states of the Klein-Gordon field with Unruh-DeWitt detectors

Albert Georg Passegger, Rainer Verch

We calculate the transition rate of an Unruh-DeWitt detector coupled to a non-equilibrium steady state (NESS) of a free massless scalar field on four-dimensional Minkowski spacetim…
