ABJM模型中的1/2- BPS威尔逊圈和涡旋

1/2-BPS Wilson Loops and Vortices in ABJM Model

Ki-Myeong Lee, Sungjay Lee

摘要:

我们通过M2-膜的Higgsing研究了1/2-BPS重粒子与ABJM模型的低能动力学,重点是对最近发现的1/2-BPS威尔逊圈算符的物理理解. 1/2-BPS重粒子的低能理论证明了U(N| N)超规范对称性,它解释了1/2-BPS威尔逊圈算符作为U(N)的完整性的新颖结构|N)超连接。我们证明了威尔逊圈算符的超对称变换可以看作是一个费米子超规范变换,这导致了它们在半超对称下的不变性。我们还认为1/2-BPS威尔逊圈算符表现为涡度为1/k的1/2-BPS涡。这样的涡旋可以自然地解释为一个膜包裹Z_k循环一次,或IIA型基本弦。

英文摘要:

We explore the low-energy dynamics of 1/2-BPS heavy particles coupled to the ABJM model via the Higgsing of M2-branes, with focus on physical understanding of the recently discovered 1/2-BPS Wilson loop operators. The low-energy theory of 1/2-BPS heavy particles turns out to have the U(N|N) supergauge symmetry, which explains the novel structure of the 1/2-BPS Wilson loop operator as a holonomy of a U(N|N) superconnection. We show that the supersymmetric transformation of the Wilson loop operator can be identified as a fermionic supergauge transformation, which leads to their invariance under half of the supersymmetry. We also argue that 1/2-BPS Wilson loop operators appear as 1/2-BPS vortices with vorticity 1/k. Such a vortex can be naturally interpreted as a membrane wrapping the Z_k cycle once, or type IIA fundamental string.
