标题： Dynamical Casimir Effect in Optically Modulated Cavities

摘要： 具有周期性振荡镜子的空腔被预测可以在一种称为动态卡西米尔效应的过程中从量子真空中激发出光子对。 在这里，我们提出并分析了一种实验布局，该布局可以在近红外光谱区域高效地调制空腔模式的有效光学长度。 建立了一个动态卡西米尔辐射的解析模型，并与实时求解麦克斯韦方程组的直接数值解的预测进行了比较。 对于现实的操作参数，预计会有显著的动态卡西米尔辐射强度。 在存在外部相干种子光束的情况下，我们预测种子光束将被放大，并且由于受激动态卡西米尔过程而出现额外的相位共轭光束。 显示英文摘要

摘要： Cavities with periodically oscillating mirrors have been predicted to excite photon pairs out of the quantum vacuum in a process known as the Dynamical Casimir effect. Here we propose and analyse an experimental layout that can provide an efficient modulation of the effective optical length of a cavity mode in the near-infrared spectral region. An analytical model of the dynamical Casimir emission is developed and compared to the predictions of a direct numerical solution of Maxwell's equations in real time. A sizeable intensity of dynamical Casimir emission is anticipated for realistic operating parameters. In the presence of an external coherent seed beam, we predict amplification of the seed beam and the appearance of an additional phase-conjugate beam as a consequence of stimulated dynamical Casimir processes.
