标题： Reflections on reflections

摘要： 通过研究基于爱因斯坦镜子的反射频率和动量，而不是以通常方式求解受动态狄利克雷边界条件限制的波动方程，来研究在(1+3)维平直时空中的完美反射镜发出的类霍金辐射。在有限尺寸的镜子情况下，辐射谱中会出现衍射图案。根据通过激光实现的类黑洞蒸发实验中相关的参数，其中霍金温度为$T_{H}\simeq 0.03$eV，镜子面积为$\mathcal{A}\simeq (50\;\mu\mathrm{m})^{2}$，估计的霍金光子产率为$N\simeq 16$/激光脉冲。 显示英文摘要

摘要： Analog Hawking radiation emitted by a perfectly reflecting mirror in (1+3)-dimensional flat spacetime is investigated. This is accomplished by studying the reflected frequency and momentum based on Einstein's mirror, instead of the canonical way of solving, if possible, wave equations subjected to a dynamical Dirichlet boundary condition. In the case of a finite-size mirror, diffraction pattern appears in the radiation spectrum. Based on the relevant parameters in the proposed Analog Black Hole Evaporation via Lasers experiment, in which the Hawking temperature $T_{H}\simeq 0.03$ eV and the mirror area $\mathcal{A}\simeq (50\;\mu\mathrm{m})^{2}$, the Hawking photon yield is estimated to be $N\simeq 16$/laser shot.
