Title Unconventional Phase Transitions in Open Markovian Quantum Systems
Abstract A number of experimental platforms for quantum simulations, from ultracold atoms to Rydberg and circuit QED arrays, can be modeled as open Markovian quantum many-body systems, where coherent (Hamiltonian) evolution competes with dissipative processes due to external environments or stochastic measurements. Out of this competition, a variety of non-trivial stationary states and dynamical behavior emerge and novel critical phenomena arise, which are unique to this open setting. In this talk I will review recent progress in this field and present our results on prototype models for strongly correlated open Markovian systems, displaying genuine nonequilibrium effects such as finite-frequency criticality and breaking of time-translational symmetry (aka quantum time-crystals), quantum multistability, or non-hermitian phase transitions.
