The dissipative model does not possess a U(1) symmetry but conserves parity. We find that 〈a j〉 = 0 always holds, so no symmetry breaking occurs. Without the onsite repulsion, the linear case is known to be critical. At the critical point the system freezes to an EPR state with infinite two mode entanglement. We show here that the correlations are rapidly destroyed whenever the repulsion is switched on. As we increase the latter, the system approaches a thermal state with an effective temperature defined in terms of the squeezing parameter in the dissipators. We characterize this transition by means of a Gutzwiller ansatz and the Gaussian Hartree–Fock–Bogoliubov approximationWe acknowledge support from the Spanish DGICYT under Projects No. FIS2011-25167 and FIS2012-33022, by the Aragon (Grupo FENOL) and the EU Project PROMISCE.Peer reviewedInstitute of Physics PublishingDirección General de Investigación Científica y Técnica, DGICT (España)CSIC-UZA - Instituto de Ciencia de Materiales de Aragón (ICMA)European CommissionConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201520152015info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Preprintinfo:eu-repo/semantics/submittedVersionhttp://hdl.handle.net/10261/121200reponame:DIGITAL.CSIC.
