动力学压缩真空中的Van der Waals力

Van der Waals force in the dynamical squeezing vacuum

基于参数动力学过程产生的压缩效应 ,利用Millonni源理论方法研究了动力学压缩真空中VanderWaals力的性质及其与真空压缩的关系。所得结果表明 :VanderWaals力的性质依赖于真空压缩的程度 ;在一定的临界条件下 ,VanderWaals力由通常的吸引性作用转化为排斥性作用。当压缩系数为零时 ,所得结果与通常文献完全一致。

Based on the squeezing effect produced by the parametric dynamics, we apply Millonni source theory to investigate VdW force in the squeezing vacuum. Our results show that the property of VdW force is dependent on the squeezing degree of vacuum; in particular, there exits a critical condition under which the ordinary attactive VdW force transforms into the repulsive force. In the special case of zero vacuum squeezing, our results coincide with those of the previous literatures.
