外场与超对称中的范数相关随机矩阵系综

Norm-dependent Random Matrix Ensembles in External Field and Supersymmetry

Thomas Guhr

摘要:

研究了外场作用下范数依赖的随机矩阵系综。这些集合中的概率密度取决于平方随机矩阵的迹,但在其他方面是任意的。执行到超空间的精确映射。本文导出了一个变换公式,它把超空间中的概率密度表示为普通空间中概率密度的一个积分。这是针对正交对称、酉对称和辛对称的。在幺正对称的情况下,得到了关联函数的一些显式结果。

英文摘要:

The class of norm-dependent Random Matrix Ensembles is studied in the presence of an external field. The probability density in those ensembles depends on the trace of the squared random matrices, but is otherwise arbitrary. An exact mapping to superspace is performed. A transformation formula is derived which gives the probability density in superspace as a single integral over the probability density in ordinary space. This is done for orthogonal, unitary and symplectic symmetry. In the case of unitary symmetry, some explicit results for the correlation functions are derived.
