论文摘要
在这项工作中，我们研究了在磁电边界附近出现的一些物理现象。为简单起见，我们仅限于平面边界的情况，该平面边界是通过具有平面外部Chern-simons样潜力的量规场之间的耦合所描述的。结果准确获得。由于Chern-Simons耦合的存在，我们计算了光子传播器进行的校正经历，并研究了固定点状电荷与磁电界边界之间的相互作用。在一个完美的镜像的极限下，在磁场和电势之间的耦合常数，我们恢复了图像方法。对于非完美的镜子，我们表明我们的图像电荷减弱，此外，还有一个图像磁性单极，其磁场强度并未表现出狄拉克字符串引入的不良和人工分歧的存在。我们还研究了板和量子粒子与自旋的相互作用。在这种情况下，由于板的磁电特性，我们具有一种电荷磁性偶极子相互作用。
In this work we study some physical phenomena that emerge in the vicinity of a magnetoelectric boundary. For simplicity, we restrict to the case of a planar boundary described by a coupling between the gauge field with a planar external Chern-Simons-like potential. The results are obtained exactly. We compute the correction undergone by the photon propagator due to the presence of the Chern-Simons coupling and we investigate the interaction between a stationary point-like charge and the magnetoelectric boundary. In the limit of a perfect mirror, where the coupling constant between the field and the potential diverges, we recover the image method. For a non perfect mirror, we show that we have an attenuated image charge and, in addition, an image magnetic monopole whose field strength does not exhibit the presence of the undesirable and artificial divergences introduced by Dirac strings. We also study the interaction between the plate and a quantum particle with spin. In this case we have a kind of charge-magnetic dipole interaction due to the magnetoelectric properties of the plate.
