动力学压缩真空中的Casimir力

Caismir force in dynamical squeezed vacuum

利用Takahashi Umezwa热场动力学方法研究了动力学压缩真空中的Casimir力 ,研究发现真空压缩与导体板间吸引力的存在互逆 ,随着时间演化 (压缩度增大 ) ,原来的微弱吸引力将迅速转化为较强的排斥力。在板间温度以及压缩系数为零的特殊情形下 。

Applying Takahashi Umezawas method of thermal field dynamics, we investigate the casimir force in the dynamical squeezed vacuum. Our results show that the Casimir force between two neutral ideal conduction plates will be weakened due to the squeezing of the vacuum. With the time evolves, the Casimir force could rapidly transform from the initial attractive one to the repulsive one. In the particular case when temperature being zero and without squeezing, the present results can be restored to the well known equations in the previous literatures.
