任意旋转不变随机矩阵系综与超对称:正交和酉辛情形

Arbitrary rotation invariant random matrix ensembles and supersymmetry: orthogonal and unitary-symplectic case

Mario Kieburg, Johan Grönqvist, Thomas Guhr

摘要:

最近,通过推广Hubbard-Stratonovich变换,将超对称方法从高斯系综推广到任意酉不变矩阵系综。在这里,我们完成这个扩展,包括任意正交和酉-辛不变矩阵合奏。结果等价于,但方法不同于超玻色化公式。我们以统一的方式表达我们的结果。我们也给出了所有一点函数的显式表达式,并讨论了高阶相关的特征。

英文摘要:

Recently, the supersymmetry method was extended from Gaussian ensembles to arbitrary unitarily invariant matrix ensembles by generalizing the Hubbard-Stratonovich transformation. Here, we complete this extension by including arbitrary orthogonally and unitary-symplectically invariant matrix ensembles. The results are equivalent to, but the approach is different from the superbosonization formula. We express our results in a unifying way. We also give explicit expressions for all one-point functions and discuss features of the higher order correlations.
