M2-brane探针动力学和复曲面对偶

M2-brane Probe Dynamics and Toric Duality

Seok Kim, Sangmin Lee, Sungjay Lee, Jaemo Park

摘要:

在最近提出的AdS 4/CFT 3对偶对M理论晶体模型的背景下,我们研究了单个M2膜探测复曲面Calabi-Yau四重奇异性的动力学。我们得到了一个有效的阿贝尔规范理论,其中物质场的电荷由晶体中环与面之间的交叉数给出。我们认为,探针理论捕捉到某些方面的CFT 3,即使真正的M2膜CFT是不太可能是一个通常的规范理论。特别是,规范理论的真空模空间与卡-丘奇点精确地重合。环面对偶,部分决议,并讨论了新的RG流的可能性。

英文摘要:

We study the dynamics of a single M2-brane probing toric Calabi-Yau four-fold singularity in the context of the recently proposed M-theory crystal model of AdS4/CFT3 dual pairs. We obtain an effective abelian gauge theory in which the charges of the matter fields are given by the intersection numbers between loops and faces in the crystal. We argue that the probe theory captures certain aspects of the CFT3 even though the true M2-brane CFT is unlikely to be a usual gauge theory. In particular, the moduli space of vacua of the gauge theory coincides precisely with the Calabi-Yau singularity. Toric duality, partial resolution, and a possibility of new RG flows are also discussed.
