Superfluidity of two- dimensional excitons in flat and harmonic traps

arXiv:0801.0152 · doi:10.1016/j.physleta.2007.01.080

Abstract

Superfluid exciton density and superfluid transition (crossover) temperature are calculated for 2D excitons in large-size flat and harmonic traps. A generalized local density approximation for the Kosterlitz-Thouless theory is developed.
