随机非对易几何中的相变

Phase Transition in Random Noncommutative Geometries

Masoud Khalkhali, Nathan Pagliaroli

摘要:

本文给出了在某些随机非对易几何的大$N$极限中存在相变的解析证明。这些几何可以表示为狄拉克算子的系综。当它们简化为单个矩阵系综时,可以应用库仑气体方法来找到经验光谱分布。我们阐述了狄拉克算子本身的大$N$谱分布的性质。此外,我们表明,这些模型表现出一个单一的和双重切割区域的某些值的序参量,并找到确切的值发生转变。

英文摘要:

We present an analytic proof of the existence of phase transition in the large $N$ limit of certain random noncommutaitve geometries. These geometries can be expressed as ensembles of Dirac operators. When they reduce to single matrix ensembles, one can apply the Coulomb gas method to find the empirical spectral distribution. We elaborate on the nature of the large $N$ spectral distribution of the Dirac operator itself. Furthermore, we show that these models exhibit both a single and double cut region for certain values of the order parameter and find the exact value where the transition occurs.
