含时介质中的电磁场量子化

Electromagnetic Field Quantization in Time-Dependent Dielectric Media

Xiao-Min Bei, Zhong-Zhu Liu

摘要:

本文提出了含时介质中电磁场的Gupta-Bleetman量子化方案。本文从麦克斯韦方程组出发,导出了适用于时变电磁场的洛仑兹规范条件的推广。利用该规范,给出了计算辐射场所有偏振态的Gupta-Bleetman方法和相应的约束条件。这种新方法不同于真空中的量子化电磁场,因为在这种情况下,非物理光子的贡献不能完全消除,这进一步导致表面电荷密度。最后,还讨论了潜在的实验测试和可能的含义。

英文摘要:

We present a Gupta-Bleuler quantization scheme for the electromagnetic field in time-dependent dielectric media. Starting from the Maxwell equations, a generalization of the Lorentz gauge condition adapted to time varying dielectrics is derived. Using this gauge, a Gupta-Bleuler approach to quantize all polarizations of the radiation field and the corresponding constraint condition are introduced. This new approach is different from the quantized electromagnetic field in vacuum in the sense that here the contributions of unphysical photons cannot be thoroughly eliminated, which further lead to a surface charge density. Finally, a discussion of potential experimental tests and possible implication is also made.
