三维超对称规范理论的算符计数和本征值分布

Operator Counting and Eigenvalue Distributions for 3D Supersymmetric Gauge Theories

Daniel R. Gulotta, Christopher P. Herzog, Silviu S. Pufu

摘要:

进一步支持了我们的猜想,即Kapustin-Willett-Yaakov矩阵模型在大N极限下的本征值分布与相应的超对称三维规范理论手征环中的算子数有关.我们证明了这种关系对于非临界R-荷和对于{ \mathcal N}=2而不是{ \mathcal N}=3的超对称性都成立,其中双基本物质场是非手征的。我们证明了,对于非临界R-收费,猜想是等价的自由能的规范理论上的三个球和体积的Sasaki流形的一部分的模空间的规范理论之间的关系。我们还调查的后果,我们的猜想手征理论的矩阵模型是没有得到很好的理解。

英文摘要:

We give further support for our conjecture relating eigenvalue distributions of the Kapustin-Willett-Yaakov matrix model in the large N limit to numbers of operators in the chiral ring of the corresponding supersymmetric three-dimensional gauge theory. We show that the relation holds for non-critical R-charges and for examples with {\mathcal N}=2 instead of {\mathcal N}=3 supersymmetry where the bifundamental matter fields are nonchiral. We prove that, for non-critical R-charges, the conjecture is equivalent to a relation between the free energy of the gauge theory on a three sphere and the volume of a Sasaki manifold that is part of the moduli space of the gauge theory. We also investigate the consequences of our conjecture for chiral theories where the matrix model is not well understood.
