论文摘要
本文致力于研究标准模型扩展(SME)的最小和非最小CPT-ODD光子扇区(SME)的固定电磁源之间的相互作用,在此,我们主要搜索Maxwell电动力学中不存在的物理现象。首先,我们考虑最小的CPT-ODD部门,其中Lorentz违规是由Carroll-Field-Jackiw(CFJ)术语引起的,即$ \simε $ \ left(k_ {af} \ right)^μ$ $ $驱动到二阶。我们认为由于存在类似点状电荷,狄拉克字符串和点状偶极子而引起的效果。在特别节目中,我们计算了琴弦之外产生的电磁场,并在洛伦兹违规情况下研究了所谓的Aharonov-Bohm绑定状态。之后,我们考虑了一个模型,其中lorentz违规是由CFJ模型的较高衍生版本产生的,即$ \simε^{μναβ}v_μa_ν\ box f_ {αβ} $,这是非Minimal Sme的CPT-ODD扇区的五个方面。对于这个高衍生模型,我们在$ v^μ$中获得了与点状电荷和稳定电流线有关的效果。为了研究原子系统中发现的某些结果的物理相关性,我们对洛伦兹违规参数使用了高估的约束。我们还使用来自原子电场的实验数据对背景矢量进行了高估。
This paper is devoted to the study of interactions between stationary electromagnetic sources for the minimal and nonminimal CPT-odd photon sector of the Standard Model Extension (SME), where we search mainly for physical phenomena not present in the Maxwell electrodynamics. First we consider the minimal CPT-odd sector, where the Lorentz violation is caused by the Carroll-Field-Jackiw (CFJ) term, namely $\simε^{μναβ}\left(k_{AF}\right)_μA_νF_{αβ}$, and we treat the Lorentz breaking parameter $\left(k_{AF}\right)^μ$ perturbatively up to second order. We consider effects due to the presence of point-like charges, Dirac strings and point-like dipoles. In special, we calculate the electromagnetic field produced outside the string and investigate the so called Aharonov-Bohm bound states in Lorentz violation context. After, we consider a model where the Lorentz violation is generated by the higher-derivative version of the CFJ model, namely $\simε^{μναβ}V_μA_ν\Box F_{αβ}$, which is a dimension five term of the CPT-odd sector of the nonminimal SME. For this higher-derivative model, we obtain effects up to second order in $V^μ$ related to the presence of point-like charges and a steady current line. We use overestimated constrains for the Lorentz violation parameters in order to investigate the physical relevance of some results found in atomic systems. We also make an overestimate for the background vectors using experimental data from the atomic electric field.
