论文摘要
洛伦兹不变质量和平均传播速度的概念已详细研究了各种多光子波包的光态。基于光电检测理论和直接的运动学，我们提出了一个身体上合理的，同时进行了严格的证明，即平均传播速度与任意多光tave-packet状态的lorentz-invariant质量概念一致。我们认为，平均传播速度小于真空中光常数的速度，并且受任意波包态在波形空间中状态幅度的几何特性的控制。为了对Lorentz-Invariant质量的固定值进行分类，我们引入了一组特定的模式，使我们能够描述其静止框架中的波包状态。
The concept of Lorenz invariant mass and mean propagation velocity have been investigated in detail for various multiphoton wave-packet states of light. Based on photodetection theory and straightforward kinematics, we presented a physically reasonable and at the same time rigorous proof that mean propagation velocity is consistent with the Lorentz-invariant mass concept for an arbitrary multiphoton wave-packet state. We argued that mean propagation velocity is less than the speed of light constant in vacuum and is governed by geometric properties of state's amplitude in wave-vector space for arbitrary wave-packet states. To classify states with different fixed values of Lorentz-invariant mass, we introduced a specific set of modes that allow us to describe the wave-packet state in its rest frame.
