论文摘要
本文研究了在半透明镜的附近，标准模型扩展（SME）的非临时CPT-CPT-EVEN量规部门的某些方面进行了研究。我们首先考虑一个模型，其中lorentz对称性破坏是由单个背景向量$ v^μ$引起的，并且我们在$ v^μ$中获得最高二阶的扰动结果。具体而言，由于镜子的存在，我们计算了量规场的修饰传播器，并分析了镜子和固定点状电荷之间的相应相互作用。我们表明，当电荷放在镜子附近时，会出现自发扭矩，这是一种新的效果，在麦克斯韦电动力学中没有对应物。我们还将这些结果与违反标量场理论的相应结果进行了比较。正如预期的那样，在完美镜子的限制情况下，我们通过图像方法恢复了相互作用。最后，我们讨论如何将这些结果扩展到更普遍的洛伦兹背景。
Some aspects of the nonbirefringent CPT-even gauge sector of the Standard Model Extension (SME), in the vicinity of a semi-transparent mirror, are investigated in this paper. We first consider a model where the Lorentz symmetry breaking is caused by a single background vector $v^μ$, and we obtain perturbative results up to second order in $v^μ$. Specifically, we compute the modified propagator for the gauge field due to the presence of the mirror and we analyze the corresponding interaction between the mirror and a stationary point-like charge. We show that when the charge is placed in the vicinity of the mirror, a spontaneous torque emerges, which is a new effect with no counterpart in Maxwell electrodynamics. We also compare these results with the corresponding ones obtained for the Lorentz violating scalar field theory. As expected, in the limiting case of perfect mirrors, we recover the interaction found via the image method. Finally, we discuss how we can extend these results for a more general Lorentz violating background.
