Vortex unbinding transition in nonequilibrium photon condensates
arXiv:2104.13203 · doi:10.1103/PhysRevA.104.043516
Abstract
We present a theoretical study of a Berezinskii-Kosterlitz-Thouless like phase transition in lattices of nonequilibrium photon condensates. Starting from linearized fluctuation theory and the properties of vortices, we propose an analytical formula for the critical point containing four fitting parameters, that captures well all our numerical simulations. We find that the ordered phase becomes more stable when driving and dissipation is increased.
