Spectrum and thermal fluctuations of a microcavity polariton Bose-Einstein condensate
arXiv:0706.3719 · doi:10.1103/PhysRevB.77.045304
Abstract
The Hartree-Fock-Popov theory of interacting Bose particles is developed, for modeling exciton-polaritons in semiconductor microcavities undergoing Bose-Einstein condensation. A self-consistent treatment of the linear exciton-photon coupling and of the exciton non-linearity provides a thermal equilibrium description of the collective excitation spectrum, of the polariton energy shifts and of the phase diagram. Quantitative predictions support recent experimental findings.
