从理论上分析了双折射微腔中二能级原子的自发辐射动力学。一个双腔支持一个形态依赖的共振，具有如此高的品质因子与局部场增强，可以实现原子和腔之间的强耦合。在充分考虑光子自由度的情况下，我们从理论上导出了传统腔QED方法中所用的原子与腔的耦合常数和辐射阻尼常数。此外，我们还证明了光子绿色函数对局部观测点的自发辐射功率谱有很强的影响。
Dynamics of the spontaneous emission from a two-level atom embedded in a bisphere microcavity is analyzed theoretically. A bisphere supports a morphology-dependent resonance having such a high quality factor with local field enhancement that the strong coupling between the atom and the cavity can be realized. By taking full account of the photon degree of freedom, we derive theoretically the coupling constant between the atom and the cavity as well as the radiation damping constants, which are used in the conventional cavity QED approach. In addition, we show that the power spectrum of the spontaneous emission at a local observation point is strongly affected by the photon Green function.
