具有一般边界条件的吸引和排斥Casimir真空能

Attractive and Repulsive Casimir Vacuum Energy with General Boundary Conditions

M. Asorey, J. M. Munoz-Castaneda

摘要:

有界域中量子场论的红外行为强烈依赖于空间边界的形状和结构。最重要的物理效应出现在真空能量的行为中。Casimir能量可以是吸引力或排斥力,这取决于边界的性质。我们计算了两个均匀平行平板间无质量标量场的真空能量,边界条件的最一般类型取决于四个参数。分析提供了一个强大的方法,以确定哪些边界条件产生吸引力或排斥卡西米尔力之间的板。在这两个政权之间的接口,我们发现一个非常有趣的家庭的边界条件,不引起任何类型的卡西米尔力。我们还表明,吸引制度持有远远超出相同的边界条件所需的两个板块的Thalth-Klich定理和最强的吸引力Casimir力出现周期性的边界条件,而最强的排斥力Casimir对应于反周期的边界条件。大多数分析的边界条件是新的,其中一些可以用超材料物理实现。

英文摘要:

The infrared behavior of quantum field theories confined in bounded domains is strongly dependent on the shape and structure of space boundaries. The most significant physical effect arises in the behaviour of the vacuum energy. The Casimir energy can be attractive or repulsive depending on the nature of the boundary. We calculate the vacuum energy for a massless scalar field confined between two homogeneous parallel plates with the most general type of boundary conditions depending on four parameters. The analysis provides a powerful method to identify which boundary conditions generate attractive or repulsive Casimir forces between the plates. In the interface between both regimes we find a very interesting family of boundary conditions which do not induce any type of Casimir force. We also show that the attractive regime holds far beyond identical boundary conditions for the two plates required by the Kenneth-Klich theorem and that the strongest attractive Casimir force appears for periodic boundary conditions whereas the strongest repulsive Casimir force corresponds to anti-periodic boundary conditions. Most of the analysed boundary conditions are new and some of them can be physically implemented with metamaterials.
