DESCRIPTION:A number of experimental platforms for quantum simulations\, f
 rom ultra cold atoms to Rydberg and circuit QED arrays\, can be modelled a
 s open Markovian quantum many body systems\, where coherent (Hamiltonian) 
 evolution competes with dissipative processes due to external environments
 .\nOut of this competition a variety of non-trivial stationary states and 
 dynamical behaviour emerge and novel critical phenomena arise which are un
 ique to this open setting\, called dissipative quantum phase transitions. 
 In this talk I will review recent experimental and theoretical progress in
  this field and present our results on prototype models of strongly correl
 ated open Markovian systems\, displaying genuine nonequilibrium effects su
 ch as finite-frequency criticality and time-crystallinity\, mulitstability
  and non-hermitian phase transitions.
