Long range order and superfluidity for bose condensed excitons

Excitonic Condensation
Part of the Lecture Notes in Physics book series (LNP, volume 57)


The problem whether a Bose-Einstein condensed system of Wannier excitons will exhibit superfluid properties is briefly reviewed. The long range order of such a system is shown to lead to a two-fluid model, which describes the superfluid flow of excitation energy. Qualitative remarks are given about the influence of perturbations, which will cause the exciton superfluidity to decay in time.
