Averages of Spectral Determinants and `Single Ring Theorem' of Feinberg and Zee

Y.V. Fyodorov, B.A. Khoruzhenko

We compute \langle det (Iz-H) (Iz-H)\dagger \rangle H in the limit of infinite matrix dimension N for complex random matrices H with invariant matrix distribution in terms of the eigenvalue distribution of the Hermitian random matrices HH\dagger . Under the assumption that 1 \over N  \ln  \langle det (Iz-H) (Iz-H)\dagger \rangle H is asymptotically equal to 1\over N \langle \ln det (Iz-H) (Iz-H)\dagger \rangle H we reproduce the eigenvalue distribution of H obtained previously by Feinberg and Zee, Nucl. Phys. B501, 643 (1997).
