摘要

在这里，我们考虑了在 1 + 1 维中与无质量标量场发生随时间变化的相互作用的不对称 δ-δ′ 镜面。利用真空中镜面的波动消散理论，我们计算了具有随时间变化的材料特性的运动δ-δ′镜面上的力。我们研究了两种不同波动源产生的一阶力，并计算了每种情况下的线性易感性。然后，我们绘制了由此产生的力。在二阶，我们还发现了对总力的独立贡献以及两个波动源之间的干涉现象所产生的力。

First- and Second-Order Forces in the Asymmetric Dynamical Casimir Effect for a Single δ − δ′ Mirror

Here, we consider an asymmetric δ−δ′ mirror undergoing time-dependent interactions with a massless scalar field in 1 + 1 dimensions. Using fluctuation-dissipation theory for a mirror in vacuum, we compute the force on a moving δ−δ′ mirror with time-dependent material properties. We investigate the first-order forces arising from the two distinct fluctuation sources and calculate the linear susceptibility in each case. We then plot the resulting forces. At the second order, we also find the independent contributions to the total force as well as the force that arises from the interference phenomena between the two fluctuation sources.
