摘要：

我们从量子场论的观点推广了爱因斯坦系数和速率方程，将光-物质相互作用的基本过程和非零Rabi频率的量子Rabi振荡统一起来。我们解析地得到了有耗谐振腔中含有热光子和相干光场注入光子的二能级系统的量子拉比振荡的多模Jaynes-Cummings模型结果。我们对这些情况下光-物质相互作用的耦合常数进行了重整化。我们的结果与Brune等人[Phys. Rev. Lett 76，1800（1996）]在这方面获得的开创性实验数据吻合得很好。我们还研究了在这方面的人口动力学应用广义爱因斯坦速率方程。

英文摘要：

We have generalized Einstein coefficients and rate equations from quantum field theoretic point of view by bringing the fundamental processes and the quantum Rabi oscillation in a single footing for the light-matter interactions for nonzero Rabi frequency. We have analytically obtained multimode Jaynes-Cummings model results for the quantum Rabi oscillations of a two-level system in a lossy resonant cavity containing (i) thermal photons and (ii) injected photons of a coherent field. We have renormalized the coupling constant for the light-matter interactions for these cases. Our results match well with the seminal experimental data obtained in this regard by Brune et al [Phys. Rev. Lett 76, 1800 (1996)]. We also have studied the population dynamics in this regard by applying the generalized Einstein rate equations.
