Nonequilibrium polariton dynamics in a Bose-Einstein condensate coupled to an optical cavity
Nonequilibrium polariton dynamics in a Bose-Einstein condensate coupled to an optical cavity
We study quasiparticle scattering effects on the dynamics of a homogeneous Bose-Einstein condensate of ultracold atoms coupled to a single mode of an optical cavity. The relevant excitations, which are polaritonlike mixed excitations of photonic and atomic density-wave modes, are identified. All the first-order correlation functions are presented by means …
