AI 中文摘要
我们表明，当光子真空破坏空间反演对称性或时间反演对称性时，传统的多极哈密顿量会发生定性修改。通过明确应用Power-Zienau-Woolley变换，我们推导了两种理想化手性光子环境下的多极哈密顿量：一种是破坏反演对称性的空间手性真空，另一种是破坏时间反演对称性的时间手性真空。在空间手性情形中，该变换会产生破坏反演的自能；在时间手性情形中，它会产生额外的类塞曼能量。我们以腔中的被俘获类氢原子和带电简谐振子作为最小示例，证明这些依赖对称性的项会导致特征性的光谱移动。我们的工作为描述手性量子电动力学中的光-物质相互作用，以及识别其对嵌入腔中的原子、分子和量子材料的依赖对称性效应，提供了通用框架。
英文摘要
We show that the conventional multipolar Hamiltonian is qualitatively modified when the photonic vacuum breaks inversion or time-reversal symmetry. By explicitly applying the Power-Zienau-Woolley transformation, we derive the resulting multipolar Hamiltonians for two idealized chiral photonic environments: a spatial-chiral vacuum, which breaks inversion symmetry, and a temporal-chiral vacuum, which breaks time-reversal symmetry. In the spatial-chiral case, the transformation generates an inversion-breaking self-energy, whereas in the temporal-chiral case it produces an additional Zeeman-like energy. Using a trapped hydrogen-like atom and a charged harmonic oscillator in cavities as minimal examples, we show that these symmetry-dependent terms lead to characteristic spectral shifts. Our work provides a general framework for describing light-matter interactions in chiral quantum electrodynamics and identifying the associated symmetry-dependent effects on cavity-embedded atoms, molecules, and quantum materials.
