摘要:

本文研究了ABJ(M)理论中定义在$1/2$ BPS Wilson线/圈上的一维缺陷SCFT。我们表明,超矩阵结构的缺陷施加了协变超矩阵表示的超荷。利用这个协变公式,我们证明了一个长的多重态的存在,其最高权状态是一个常数超矩阵算子。在弱耦合下,我们用微扰理论研究了这个算子,证实了它获得了一个非平凡的反常维数。在强耦合下,我们推测该算符与AdS $_4\times \mathbb{CP}_3$中基本开弦在经典$1/2$ BPS解附近涨落的最低束缚态是对偶的.令人意外的是,该算子也出现在玻色子和费米子威尔逊圈之间的上同调等价中。我们还讨论了在无限威尔逊线上微扰计算中所产生的一些正则化的微妙之处。

英文摘要:

We investigate the one-dimensional defect SCFT defined on the $1/2$ BPS Wilson line/loop in ABJ(M) theory. We show that the supermatrix structure of the defect imposes a covariant supermatrix representation of the supercharges. Exploiting this covariant formulation, we prove the existence of a long multiplet whose highest weight state is a constant supermatrix operator. At weak coupling, we study this operator in perturbation theory and confirm that it acquires a non-trivial anomalous dimension. At strong coupling, we conjecture that this operator is dual to the lowest bound state of fluctuations of the fundamental open string in AdS$_4\times \mathbb{CP}_3$ around the classical $1/2$ BPS solution. Quite unexpectedly, this operator also arises in the cohomological equivalence between bosonic and fermionic Wilson loops. We also discuss some regularization subtleties arising in perturbative calculations on the infinite Wilson line.
