光锋上的卡西米尔力

Casimir force on a light front

S. S. Chabysheva, J. R. Hiller

摘要:

根据不同的观点,卡西米尔力产生于量子真空能量的变化,因为边界条件被改变,或者作为形成这些边界条件的材料中原子之间的相互作用。对这种构型的标准分析通常是用普通的等时(闵可夫斯基)坐标来进行的。然而,物理学与坐标选择无关,基于光阵面坐标的分析(其中$x^+\equiv t+z/c$扮演时间的角色)同样有效。在简要的历史介绍之后,我们举例说明并比较了卡西米尔力的等时计算和光阵面计算。

英文摘要:

Depending on the point of view, the Casimir force arises from variation in the energy of the quantum vacuum as boundary conditions are altered or as an interaction between atoms in the materials that form these boundary conditions. Standard analyses of such configurations are usually done in terms of ordinary, equal-time (Minkowski) coordinates. However, physics is independent of the coordinate choice, and an analysis based on light-front coordinates, where $x^+\equiv t+z/c$ plays the role of time, is equally valid. After a brief historical introduction, we illustrate and compare equal-time and light-front calculations of the Casimir force.
