A number of experimental platforms for quantum simulations, from ultra cold atoms to Rydberg and circuit QED arrays, can be modelled 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 behaviour 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 many-body models for open Markovian systems, displaying genuine nonequilibrium effects such as finite-frequency criticality and breaking of time-translational symmetry (aka dissipative time-crystals), quantum mulitstability or measurement-induced entanglement transitions.
