E. R. Bezerra de Mello, M. B. Cruz

AI总结:

本文在量子场论框架下,研究两平行板间实大质量标量场通过CPT-even类以太方法与正交恒定向量耦合导致的洛伦兹对称性破坏,分析了时空各向异性对Casimir能量和压力的修改。

摘要:

在这项工作中,我们考虑了一个在量子场论方法中呈现洛伦兹对称性破坏的理论模型。所采用的理论模型由一个限制在两块大平行板之间的区域中的实大质量标量量子场组成。洛伦兹对称性破坏通过CPT-even、类以太方法引入,考虑标量场的导数与两个正交恒定向量之间的直接耦合。本文的主要目标是分析由于这些耦合导致的时空各向异性对Casimir能量和压力造成的修改。标量量子场在板之间的限制通过在板上施加边界条件来实现。

英文摘要:

In this work, we consider a theoretical model that presents violation of the Lorentz symmetry in the approach of Quantum Field Theory. The theoretical model adopted consists of a real massive scalar quantum field confined in the region between two large parallel plates. The Lorentz symmetry violation is introduced by CPT-even, aether-like approach, considering a direct coupling between the derivative of the the scalar field with two orthogonal constant vectors. The main objective of this paper is to analyze the modification on the Casimir energy and pressure caused by the anisotropy of the space-time as consequence of these couplings. The confinement of the scalar quantum field between the plates is implemented by the imposition boundaries conditions on them.
