标题： Material boundaries in Carroll-Field-Jackiw Lorentz-violating electrodynamics

摘要： 本文研究了在存在完美导电板（完美镜面）的情况下，最小标准模型扩展（SME）中CPT奇光子部分的某些方面。 所考虑的部分由Carroll-Field-Jackiw（CFJ）电动力学描述，其中洛伦兹破坏是由于一个称为$\left(k_{AF}\right)^{\mu}$的单个背景矢量的存在，我们将其微扰处理到二阶。 具体而言，我们推导了由于完美镜面存在而产生的电磁场的修正传播子，并研究了镜面与静止点电荷之间的相应相互作用。 我们的结果表明，当电荷靠近镜面时，会产生自发扭矩，这是洛伦兹对称性破缺的独特效应。 此外，我们证明当背景矢量只有垂直于镜面的分量时，该理论的镜像方法是适用的。 显示英文摘要

摘要： This paper investigates certain aspects of the CPT-odd photon sector of the minimal Standard Model Extension (SME) in the presence of a perfectly conducting plate (perfect mirror). The considered sector is described by Carroll-Field-Jackiw (CFJ) electrodynamics, where Lorentz violation is due to the presence of a single background vector denoted as $\left(k_{AF}\right)^{\mu}$, which we treat perturbatively up to second order. Specifically, we derive the modified propagator for the electromagnetic field due to the presence of the perfect mirror, and we study the corresponding interaction between the mirror and a stationary point-like charge. Our results reveal that when the charge is positioned near the mirror, a spontaneous torque emerges, which is a unique effect of Lorentz symmetry breaking. Additionally, we demonstrate that the image method for this theory is applicable when the background vector has only the component perpendicular to the mirror.
