摘要:

本文研究了由两个相互作用的实标量场和复标量场组成的系统的Casimir能量密度、圈修正和拓扑质量生成。所考虑的相互作用是以复场模平方与实场平方乘积形式的四次相互作用。此外,还考虑了与每个场相关的自相互作用。在该理论中,实标量场被约束为始终满足周期性条件,而复场在一种情况下满足准周期条件,在另一种情况下满足混合边界条件。针对所考虑的有质量和无质量标量场,解析地评估了Casimir能量密度、圈修正和拓扑质量。还分析了可能的不同稳定真空态及相应的稳定性条件。为了更好地理解我们的研究,还给出了一些图。我们在此用于执行此类研究的形式体系是有效势,在量子场论中它通过路径积分被写成圈展开的形式。

英文摘要:

In this paper the Casimir energy density, loop corrections, and generation of topological mass are investigated for a system consisting of two interacting real and complex scalar fields. The interaction considered is the quartic interaction in the form of a product of the modulus square of the complex field and the square of the real field. In addition, it is also considered the self-interaction associated with each field. In this theory, the scalar field is constrained to always obey periodic condition while the complex field obeys in one case a quasiperiodic condition and in other case mixed boundary conditions. The Casimir energy density, loop corrections, and topological mass are evaluated analytically for the massive and massless scalar fields considered. An analysis of possible different stable vacuum states and the corresponding stability condition is also provided. In order to better understand our investigation, some graphs are also presented. The formalism we use here to perform such investigation is the effective potential, which is written as loop expansions via path integral in quantum field theory.
