Anomalous dissipative transitions

Ramasubramanian Chitra

In this talk, we will explore scenarios where a weak coupling to a nonthermal environment profoundly alters the phase diagram of the closed system, giving rise to a special class of dissipation-induced transitions. Here, an infinitesimal dissipation suffices to knock the system out of its ground state and stabilize a higher-energy stationary state, often overwhelming the symmetry breaking tendencies of the system. We demonstrate the ubiquitousness of such dissipative
stabilzation of excited states in Dicke like light-matter coupled models and the paradigmatic parametric Kerr resonator. We show how dissipation leads to rich physics and discuss their consequences for experiments.
