论文摘要
四维n = 4个超级阳米尔，具有编成一个的一个缺陷，破坏了一半的超对称性，这是在全息图中的D3/D5相交的场理论描述时出现的。这是全息图中最早的，最广泛的研究和常用系统之一。在本说明中，我们为该系统提供了完整的R-对称性对称性超对称变化。我们还提供超电流并计算相应增压的代数，并获得全套中央电荷。我们表明，保留一半超对称性的一半的磁性有限能源场配置是对扩展的Bogomolny方程的一种新形式的解决方案，其中缺陷场在该方程的类似NAHM的部分中起着跳跃数据的作用。在附录中，我们解释了结果与文献中基于超空间的配方之间的联系。
Four-dimensional N=4 super Yang-Mills, with a codimension-one defect breaking half of the supersymmetry, arises as the field theory description of the D3/D5 intersection in the holographic limit. This is one of the earliest, most extensively studied, and commonly used systems in holography. In this note we give the full R-symmetry-covariant supersymmetry variations for this system. We also provide the supercurrents and compute the algebra of the corresponding supercharges, obtaining the full set of central charges. We show that magnetically charged finite-energy field configurations preserving half of the supersymmetry are solutions to a new form of the extended Bogomolny equations, in which the defect fields play the role of jumping data for the Nahm-like part of the equations. In the appendices, we explain the connection between our results and the superspace-based formulations in the literature.
