Abstract: We present a generic model for the description of non-equilibrium Bose-Einstein condensates, suited for the modelling of non-resonantly pumped polariton condensates in a semiconductor microcavity. The excitation spectrum and scattering of the non-equilibrium condensate with a defect are discussed. Model and elementary excitation spectrumDue to the finite polariton lifetime, the nature of polariton condensates [1] is fundamentally different from that of their superfluid 4 He and atomic Bose-Einstein condensate…
