We show that short-range correlations have a dramatic impact on thesteady-state phase diagram of quantum driven-dissipative systems. This effect,never observed in equilibrium, follows from the fact that ordering in thesteady state is of dynamical origin, and is established only at very longtimes, whereas in thermodynamic equilibrium it arises from the properties ofthe (free) energy. To this end, by combining the cluster methods extensivelyused in equilibrium phase transitions to quantum trajectories andtensor-network techniques, we extend them to nonequilibrium phase transitionsin dissipative many-body systems. We analyze in detail a model of spin-1=2 on alattice interacting through an XYZ Hamiltonian, each of them coupled to anindependent environment that induces incoherent spin flips. In the steady-statephase diagram derived from our cluster approach, the location of the phaseboundaries and even its topology radically change, introducing reentrance ofthe paramagnetic phase as compared to the single-site mean field wherecorrelations are neglected. Furthermore, a stability analysis of the clustermean field indicates a susceptibility towards a possible incommensurateordering, not present if short-range correlations are ignored.
