论文摘要
我们研究了动态casimir效应的随机版本，计算了由其中一个壁的随机运动产生的腔体内的粒子创造。我们首先提出运动幅度的计算扰动。我们将随机粒子的创造与确定性对应物进行比较。然后，我们使用多个比例分析的随机版本超越了扰动评估，该版本考虑了随机参数共振。我们强调由随机运动引起的不同模式之间耦合的相关性。在单模近似中，方程式与描述宇宙学中描述随机粒子创建的方程式相似，我们使用多尺度分析进行了重新练习。
We study a stochastic version of the dynamical Casimir effect, computing the particle creation inside a cavity produced by a random motion of one of its walls. We first present a calculation perturbative in the amplitude of the motion. We compare the stochastic particle creation with the deterministic counterpart. Then we go beyond the perturbative evaluation using a stochastic version of the multiple scale analysis, that takes into account stochastic parametric resonance. We stress the relevance of the coupling between the different modes induced by the stochastic motion. In the single-mode approximation, the equations are formally analogous to those that describe the stochastic particle creation in a cosmological context, that we rederive using multiple scale analysis.
