基于模糊标量场理论的多迹矩阵模型

A Multitrace Matrix Model from Fuzzy Scalar Field Theory

Denjoe O'Connor, Christian Saemann

摘要:

我们提出了模糊球上的标量场理论的分析方法,该方法已在arXiv:0706.2493 [hep-th]中开发。这种方法是基于考虑的动力学项的微扰展开的配分函数。在二阶截断这种扩展后,得到多道矩阵模型,它允许鞍点法的应用。结果与文献中的数值结果一致。

英文摘要:

We present the analytical approach to scalar field theory on the fuzzy sphere which has been developed in arXiv:0706.2493 [hep-th]. This approach is based on considering a perturbative expansion of the kinetic term in the partition function. After truncating this expansion at second order, one arrives at a multitrace matrix model, which allows for an application of the saddle-point method. The results are in agreement with the numerical findings in the literature.
