标题： Arbitrary gauge quantisation of light-matter theories with time-dependent constraints

摘要： 我们提供了一个用于量化具有时间依赖性完整约束的光-物质理论的一般框架。 除非在拉格朗日层面从一开始就存在时间依赖性，否则不同的规范通常会产生非等价的正则理论。 无旋规范被定义为在哈密顿量层面引入时间依赖性时也能产生正确理论的规范。 我们统一了现有文献中此类规范的例子。 特别是，我们表明，在描述时间依赖性光-物质相互作用时，库仑规范通常不是无旋的，因此它并不享有任何特殊地位，这与Phys. Rev. A 107, 013722 (2023)和Phys. Rev. Research 3, 023079 (2021)中的结论相矛盾，同时确认了Phys. Rev. Research 3, 013116 (2021)中之前处理和结论。 显示英文摘要

摘要： We provide a general framework for the quantisation of light-matter theories with time-dependent holonomic constraints. Unless time dependence is present from the outset at the Lagrangian level, different gauges generally produce non-equivalent canonical theories. The irrotational gauge is defined as that which also yields a correct theory when time dependence is introduced at the Hamiltonian level. We unify examples of such gauges found in existing literature. In particular, we show that for describing time-dependent light-matter interactions the Coulomb gauge is not generally irrotational, so it does not enjoy any special status, contradicting the conclusions in Phys. Rev. A 107, 013722 (2023) and Phys. Rev. Research 3, 023079 (2021), while reaffirming the prior treatment and conclusions reported in Phys. Rev. Research 3, 013116 (2021).
