Deviation from Kibble-Zurek scenario in nonequilibrium transition

Abstract

We investigate the process of condensation of exciton-polaritons in a one-dimensional nanowire, predicting spontaneous formation of domains of uncondensed excitons and condensed polaritons. We demonstrate a universal scaling law for the density of domains, which results from the competition between characteristic timescales present in the system. However, we find that the system does not follow the standard Kibble-\.Zurek scenario of a nonequilibrium phase transition.
