Lorentz invariant photon number density
摘要：
导出了光子数密度的洛伦兹不变正定表达式，它是偏振敏感位置本征矢量与光子波函数的不变标量积的绝对平方。结果发现，这个标量积是独立的波函数的形式选择和归一化的正频率矢势-电场对是一个方便的选择波函数在物质的存在。描述局部化状态的数字幅度是在局部化和检测被视为同时的时刻的δ函数。
英文摘要：
A Lorentz invariant positive definite expression for photon number density is derived as the absolute square of the invariant scalar product of a polarization sensitive position eigenvector and the photon wave function. It is found that this scalar product is independent of the form chosen for the wave function and that the normalized positive frequency vector potential-electric field pair is a convenient choice of wave function in the presence of matter. The number amplitude describing a localized state is a delta-function at the instant at which localization and detection are seen as simultaneous.
