Quantum Theory of Nonlinear Semiconductor Microcavity Luminescence Explaining “Boser” Experiments

摘要: Photoluminescence experiments from semiconductor quantum wells inside a microcavity are reported which exhibit thresholdlike transition already below lasing. A fully mechanical theory for an interacting system of photons and Coulomb-correlated well electrons holes is presented. The experimental results previously attributed to bosonic condensation explained consistently in terms fermionic electron-hole correlations.
