Miscible–immiscible transition and nonequilibrium scaling in two-component driven open condensate wires

Year: 2017

Type: article

Abstract: We investigate the steady state phase diagram of two-component driven open condensates (DOCs) in one dimension. We identify a miscible–immiscible transition which is predominantly driven by gapped density fluctuations and occurs upon increasing the inter-component dissipative coupling. Below the transition in the miscible phase, we find the effective long wavelength dynamics to be described by a two-component Kardar–Parisi–Zhang (KPZ) equation that belongs to the nonequilibrium universality class of the one-dimensional single-component KPZ equation at generic choices of parameters. Our results are relevant for different experimental realizations for two-component DOCs in exciton–polariton systems.
