Supermode-density-wave-polariton condensation with a Bose–Einstein condensate in a multimode cavity
Abstract
When a single mode optical cavity is coupled to a Bose-Einstein condensate, one usually observes a single mode of light when strongly pumped. Here the authors observe a supermode in the output of a multimode cavity and relate this to a signature of a nonequilibrium condensation phase transition.
