摘要
The quantum dynamics of an exciton dressed by acoustic pnonons in an optically driven quantum dotsemiconductor microcavity at finite temperatures is investigated theoretically by quantum optics methods. It is shown that the temperature dependence of the vacuum Rabi splitting is 2√2g×exp[ - ∑qλq（Nq＋1/2）],where Nq=1/[exp（ωq/kBT）-1] is the phonon population, g is the single-photon Rabi frequency, and λq corresponds to exciton-phonon coupling.
采用量子光学和极化子正则变换的方法研究了有限温度下半导体微腔中单量子点的激子动力学行为,并解析得到了激子真空拉比分裂随温度变化的函数关系.
