Marc-Thierry Jaekel, Serge Reynaud

AI总结:

本文研究二维时空中两个点状镜子在标量场真空态下的卡西米尔力涨落,利用线性响应理论推导运动力,发现其在腔模频率处共振增强,并将其解释为压缩场产生的力学后果。

摘要:

我们研究在二维时空中标量场的真空态里放置两个点状镜子的情形。通过满足幺正性、因果性和高频透明条件的透射率与反射率函数来描述镜子上的散射,我们计算了施加在两个静止镜子上的卡西米尔力的涨落。我们使用线性响应理论推导出当一个镜子运动或另一个镜子运动时施加在其中一个镜子上的运动力。我们证明这些力可以在对应于腔模的频率处被共振增强。我们将它们解释为产生压缩场的力学后果。

英文摘要:

We study the situation where two point like mirrors are placed in the vacuum state of a scalar field in a two-dimensional spacetime. Describing the scattering upon the mirrors by transmittivity and reflectivity functions obeying unitarity, causality and high frequency transparency conditions, we compute the fluctuations of the Casimir forces exerted upon the two motionless mirrors. We use the linear response theory to derive the motional forces exerted upon one mirror when it moves or when the other one moves. We show that these forces may be resonantly enhanced at the frequencies corresponding to the cavity modes. We interpret them as the mechanical consequence of generation of squeezed fields.
