摘要:

本文研究了空间非均匀性存在下的标量场的场论模型。用位置相关的质量项描述了标量场与缺陷的相互作用。在这个模型中,我们推导了两个有限宽度的反射镜的相互作用,建立了该模型与Lifshitz公式的对应关系,并构造了限制程序,以获得单个反射镜的有限自能,而无需任何归一化条件。

英文摘要:

We study the field theoretical model of a scalar field in presence of spacial inhomogeneities in form of one and two finite width mirrors (material slabs). The interaction of the scalar field with the defect is described with position-dependent mass term. Within this model we derive the interaction of two finite width mirrors, establish the correspondence of the model to the Lifshitz formula and construct limiting procedure to obtain finite self-energy of a single mirror without any normalization condition.
