给出了一种研究球腔中原子或辐射偶极子的腔量子电动力学的一般形式。计算了特定情况下的原子能级位移和修正的偶极衰变率。特别地，位于空球（半径a）中心的原子的能量移动对于大ka为1/a 4，对于小ka为1/a 2，其中k是波数。我们将这些变化分别归因于延迟的Casimir-Polder相互作用和与状态无关的真空场贡献。© 1996美国物理学会。
We present a general formalism for studying the cavity quantum electrodynamics for an atom or a radiating dipole inside a hollow spherical cavity. The atomic-energy-level shifts and the modified dipolar decay rates are calculated in specific cases. In particular, the energy shifts for an atom located at the center of an empty sphere (radius a) vary as 1/a 4 for large ka and 1/a 2 for small ka, where k is the wave number. We attribute these variations to the retarded Casimir-Polder interaction and the state-independent vacuum-field contribution, respectively.© 1996 The American Physical Society.
