Norm-dependent random matrix ensembles in external field and supersymmetry

Guhr, Thomas LU (2006) In Journal of Physics A: Mathematical and General 39(40). p.12327-12342
Abstract
The class of norm-dependent random matrix ensembles is studied in the presence of an external field. The probability density of the ensemble 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 symmetries. In the case of unitary symmetry, some explicit results for the correlation functions are derived.
