SUMMARY:Correlations in driven-dissipative quantum systems
DESCRIPTION:Featuring Michiel Wouters\, University of Antwerp\nHosted by: A
	natoli Polkovnikov\, Dries Sels\n\nPart of the Condensed Matter Theory Semi
	nar Series.\n\nRecent advances in experimental platforms for photonic quant
	um simulators (microcavity polaritons and superconducting circuits) have sp
	urred the interest in the theory of driven-dissipative quantum systems. The
	 long time steady state of such systems is not given by a Boltzmann-Gibbs d
	istribution\, but has to be found by solving a Lindblad master equation. \n
	\nIn this talk\, I will discuss two topics: for weakly interacting systems\
	, the imprint of Landau-Beliaev scattering on the steady state distribution
	 of a 1D photonic Hubbard model in the weakly interacting regime and the fa
	ilure of the truncated Wigner approximation to capture this feature. For st
	rongly interacting systems\, I will present results obtained within the Gut
	zwiller approximation to the quantum trajectories of a dissipative XYZ mode
	l. We show that a ferromagnetic to paramagnetic phase transition\, that is 
	missing within a mean field treatment\, is recovered within our approach.
