论文摘要
我们研究Casimir效应在$ u（1）$ gauge场的量子动力学理论框架中的平衡和非平衡光子气体中。我们首先从麦克斯韦方程中得出光子数分布的传输，约束和量规固定方程，然后通过考虑系统表面的边界条件来计算有限系统的能量变化和Casimir力。考虑两个绝热板时，光子在平衡状态下的热运动抑制了真空中的Casimir力。在非平衡状态下，光子诱导的casimir力振荡并随着时间的流逝而衰减，最终消失。
We study Casimir effect in equilibrium and non-equilibrium photon gas in the frame of quantum kinetic theory for $U(1)$ gauge field. We derive first the transport, constraint and gauge fixing equations for the photon number distribution from Maxwell's equations, and then calculate the energy variation and Casimir force for a finite system by considering boundary condition on the surface of the system. The Casimir force in vacuum is suppressed by the thermal motion of photons in equilibrium state, when considering two adiabatic plates. In non-equilibrium state, the photon induced Casimir force oscillates and decays with time and finally disappears.
