SUMMARY:Séminaire du LPTMS: José Lebreuilly - LPTMS\, salle 201\, 2ème 
 étage\, Bât 100\, Campus d'Orsay - 24 Avr 18 11:00
DESCRIPTION:Stabilizing zero temperature quantum phases and incompressible 
 states of light via non-Markovian reservoir engineering\nJosé Lebreuilly 
 (Laboratoire Pierre Aigrain\, ENS\, Paris)\nWe study the possibility of st
 abilizing strongly correlated quantum fluids of light in driven-dissipativ
 e devices through novel non-Markovian reservoir engineering techniques. Th
 is approach allows to compensate losses and refill selectively the photoni
 c population so to sustain a desired steady-state. It relies in particular
  on the use of a frequency-dependent incoherent pump which can be implemen
 ted\, e.g.\, via embedded two-level systems maintained at a strong inversi
 on of population. As specific applications of these methods\, we discuss t
 he generation of a photonic Mott Insulator (MI). As a first step\, we pres
 ent the case of a narrow band emission spectrum and show how this allows f
 or the stabilization of MI states under the condition that the photonic st
 ates are relatively flat in energy. As soon as the photonic bandbwidth bec
 omes comparable to the emission linewidth\, important non-equilibrium sign
 atures and entropy generation appear\, and a novel dissipative phase trans
 ition from a Mott Insulating state toward a superfluid (SF) phase is unvei
 led. As a second step\, we present a more advanced configuration based on 
 reservoirs with a broadband frequency distribution\, and we highlight the 
 potential of this configuration for the quantum simulation of equilibrium 
 quantum phases at zero temperature with tunable chemical potential. As a p
 roof of principle we establish the applicability of our scheme to the Bose
 -Hubbard model by confirming the presence of a perfect agreement with the 
 ground-state predictions both in the MI and SF regions\, and more generall
 y in all parts of the parameter space.
