Casimir效应作为耗散系统的模求和

The Casimir effect as a sum-over-modes in dissipative systems

Francesco Intravaia, Ryan Behunin

摘要:

本文的目的是表明,在开放系统的框架内的总和模式的方法á la卡西米尔导致卡西米尔自由能的Lifshitz公式。利用Ford,Lewis & O'Connell的显着公式,得到了适用于任意几何的一般结果。此外,我们解决的可能性,获得卡西米尔能源作为一个复杂的“模式”的总和。在这种情况下,我们表明,标准的总和模式公式必须适当地推广,以避免非物理复杂的能量。最后,我们将我们的结果应用到几个标准的例子。

英文摘要:

The aim of this paper is to show that within the open-system framework the sum-over-modes approach á la Casimir leads to the Lifshitz formula for the Casimir free energy. A general result applicable to arbitrary geometries is obtained through the use of Ford, Lewis, & O'Connell's remarkable formula. Additionally, we address the possibility for obtaining the Casimir energy as a sum over complex "modes". We show in this case that the standard sum-over-modes formula must be suitably generalized to avert unphysical complex energies. Finally, we apply our results to several standard examples.
