Lorentz对称性破坏模型中的电磁Casimir效应

Electromagnetic Casimir effect in a Lorentz symmetry violation model

Dêivid R. da Silva, E. R. Bezerra de Mello

摘要:

在本文中,我们研究了电磁Casimir效应的背景下的洛伦兹对称性破坏。两种不同的方法被认为是:第一个是基于Horava-Lifshitz方法,它明确提出了一个空间-时间的各向异性,而第二个是一个模型,包括更高的导数的场强张量和优先方向的空间-时间。我们假设电磁场服从两大平行板上的标准边界条件。我们的主要目标是调查如何卡西米尔能量和压力的修改在两个洛伦兹破坏的情况。

英文摘要:

In this paper, we study the electromagnetic Casimir effects in the context of Lorentz symmetry violations. Two distinct approaches are considered: the first one is based on Horava-Lifshitz methodology, which explicitly presents a space-time anisotropy, while the second is a model that includes higher-derivatives in the field strength tensor and a preferential direction in the space-time. We assume that the electromagnetic field obeys the standard boundary conditions on two large parallel plates. Our main objectives are to investigate how the Casimir energy and pressure are modified in both Lorentz violation scenarios.
