动态Casimir辐射引起的摩擦力的量子涨落

Quantum fluctuations of the friction force induced by the dynamical Casimir emission

Salvatore Butera, Iacopo Carusotto

摘要:

本文研究了一个在谐振腔中的动态Casimir效应的量子模型。研究了动态Casimir辐射对运动镜面摩擦力的量子涨落及其对镜面振荡量子态的影响。可观察到的签名的相互作用的非线性性质的有效镜腔耦合和发射的光子的离散性指出,特别是作为一个快速扩散的镜振荡相位。这些结果被解释在弯曲时空的量子场论的语言作为一个故障的标准半经典理论的反反应。

英文摘要:

We study a quantum model of dynamical Casimir effect in an optical cavity enclosed by a freely moving mirror attached to a harmonic spring. The quantum fluctuations of the friction force exerted by the dynamical Casimir emission onto the moving mirror are investigated, as well as their consequences on the quantum state of the mirror oscillation. Observable signatures of the interplay of the nonlinear nature of the effective mirror-cavity coupling and of the discreteness of the emitted photons are pointed out, in particular as a fast diffusion of the mirror oscillation phase. These results are interpreted in the language of quantum field theories on curved space-times as a breakdown of the standard semiclassical theory of the backreaction.
