模糊CP ^n上标量场的多迹矩阵模型

The Multitrace Matrix Model of Scalar Field Theory on Fuzzy CP^n

Christian Saemann

摘要:

本文将模糊CP^n上的标量量子场论在逆温度下展开到三阶。利用群论方法,我们将结果改写为多迹矩阵模型。通过鞍点法计算了该矩阵模型的配分函数,并分析了不同n时的相图。我们的结果证实了先前对CP ^[1]相图的数值研究结果。

英文摘要:

We perform a high-temperature expansion of scalar quantum field theory on fuzzy CP^n to third order in the inverse temperature. Using group theoretical methods, we rewrite the result as a multitrace matrix model. The partition function of this matrix model is evaluated via the saddle point method and the phase diagram is analyzed for various n. Our results confirm the findings of a previous numerical study of this phase diagram for CP^1.
