Non-equilibrium physics of Rydberg lattices in the presence of noise and dissipative processes

摘要: We study the non-equilibrium dynamics of driven spin lattices in presence decoherence caused by either laser phase noise or strong decay. In first case, we discriminate between correlated and uncorrelated explore their effect on mean density Rydberg states full counting statistics (FCS). find that while is almost identical both cases, FCS differ considerably. The main method employed Langevin equation (LE) but for sake efficiency certain regimes, use a Markovian master Monte Carlo rate equations, respectively. second consider dissipative systems with more general power-law interactions. determine diagram steady state analyse its generation using equations. contrast to nearest-neighbour models, there no transition long-range-ordered phases realistic interactions resonant driving. Yet, finite detunings, show can undergo antiferromagnetic (AF) phase. identify advantages equations over field (MF) predictions.
