实Ginibre系综中的特征多项式

Characteristic polynomials in real Ginibre ensembles

G. Akemann, M. J. Phillips, H. -J. Sommers

摘要:

我们计算了非对称随机矩阵的实Ginibre系综的两个特征多项式的平均值,以及它的手征对应项。被认为是二次型,它们确定了一个反对称核,从这个核可以导出所有复特征值相关。我们的结果是在一个非常简单的方式,而不去的本征值表示,是完全新的手征的情况下。它们适用于部分对称的高斯系综,其内核分别以Hermite和Laguerre多项式给出,取决于不对称参数。这使我们能够插值之间的最大不对称的真实Ginibre和高斯正交包络,以及他们的手征对手。

英文摘要:

We calculate the average of two characteristic polynomials for the real Ginibre ensemble of asymmetric random matrices, and its chiral counterpart. Considered as quadratic forms they determine a skew-symmetric kernel from which all complex eigenvalue correlations can be derived. Our results are obtained in a very simple fashion without going to an eigenvalue representation, and are completely new in the chiral case. They hold for Gaussian ensembles which are partly symmetric, with kernels given in terms of Hermite and Laguerre polynomials respectively, depending on an asymmetry parameter. This allows us to interpolate between the maximally asymmetric real Ginibre and the Gaussian Orthogonal Ensemble, as well as their chiral counterparts.
