Abstract
We study the out-of-equilibrium dynamics of dissipative gases of atoms excited to two or more high-lying Rydberg states. This situation bears interesting similarities to classical binary (in general p-ary) mixtures of particles. The effective forces between the components are determined by the inter-level and intra-level interactions of Rydberg atoms. These systems permit to explore new parameter regimes which are physically inaccessible in a classical setting, for example one in which the mixtures exhibit non-additive interactions. In this situation the out-of-equilibrium evolution is characterized by the formation of metastable domains that reach partial equilibration long before the attainment of stationarity. In experimental settings with mesoscopic sizes, this collective behavior may in fact take the appearance of dynamic symmetry breaking.
Highlights
Dissipative Rydberg gases enable the exploration of a great variety of out-of-equilibrium phenomena
Dynamical effects that have been theoretically predicted include kinetic constrains [1], crystallization [2,3,4,5,6], bistability [7,8,9], spatial correlations and density waves [10], aggregation [11, 12], antiferromagnetic order [13], non-equilibrium phase transitions [14], classical and quantum glassiness [15], many-body entanglement [16, 17] and self-similarity [18, 19]. Some of these phenomena, including the build-up of correlations [20,21,22], crystallization [23], kinetic constraints [24], aggregation [25, 26] and bimodality [25, 27, 28] have already been observed, which highlights the power of Rydberg gases for investigating non-equilibrium quantum dynamics
We deliberately focus on a situation where exchange interactions can be omitted, which can be achieved by a specific choice of Rydberg states [40]
