论文摘要

在本文中,我们在纯的Abelian仪表理论中构建了一个带有有限能量的带电孤子,没有三角洲功能来源。具体而言,我们首先考虑具有麦克斯韦术语和l evel $ n $ cs术语的三维ABELIAN仪表理论。我们找到了一个静态解决方案,该解决方案携带$ n $,Angular Momment $ \ frac {n} {2} $,其半径为$ N $独立。但是,该溶液具有不同的能量。类似于用BI动作替换4维的麦克斯韦作用,这使得为3维理论提供了点电荷有限的经典能量,该理论包括CS术语,此类替换会导致上述解决方案的有限能量。我们将此孤子称为CSBION解决方案,代表了Maxwell理论的基本能量版本(在4个维度上)。在3个维度中,BI+CS动作具有带有有限能量的静电溶液,因此没有来源,因此是孤子溶液。与其麦克斯韦前任类似的CSBION具有收费$ n $,与$ n $成比例的角度动量和$ n $无关的半径。我们还介绍了麦克斯韦理论的其他非线性修改,该理论接受了类似的孤子。 CSBION可能在各种全息方面都有意义。特别是,它可以描述D6-Brane在压实的D4-Brane背景中包装$ S^4 $。我们认为,CSBION可能在2+1个维度(例如石墨烯片)的凝结物质系统中发挥作用。

In this paper, we construct a charged soliton with a finite energy and no delta function source in a pure Abelian gauge theory. Specifically, we first consider the 3-dimensional Abelian gauge theory, with a Maxwell term and a l evel $N$ CS term. We find a static solution that carries charge $N$, angular momentum $\frac{N}{2}$ and whose radius is $N$ independent. However, this solution has a divergent energy. In analogy to the replacement of the 4 dimensional Maxwell action with the BI action, which renders the classical energy of a point charge finite, for the 3 dimensional theory which includes a CS term such a replacement leads to a finite energy for the solution of above. We refer to this soliton as a CSBIon solution, representing a finite energy version of the fundamental (sourced) charged electron of Maxwell theory in 4 dimensions. In 3 dimensions the BI+CS action has a static charged solution with finite energy and no source, hence a soliton solution. The CSBIon, similar to its Maxwellian predecessor, has a charge $N$, angular momentum proportional to $N$ and an $N$-independent radius. We also present other nonlinear modifications of Maxwell theory that admit similar solitons. The CSBIon may be relevant in various holographic scenarios. In particular, it may describe a D6-brane wrapping an $S^4$ in a compactified D4-brane background. We believe that the CSBIon may play a role in condensed matter systems in 2+1 dimensions like graphene sheets.
