Abstract

We calculate the kk-point generating function of the correlated Jacobi ensemble using supersymmetric methods. We use the result for complex matrices for k=1k=1 to derive a closed-form expression for eigenvalue density. For real matrices we obtain the density in terms of a twofold integral that we evaluate numerically. For both expressions we find agreement when comparing with Monte Carlo simulations. Relations between these quantities for the Jacobi and the Cauchy-Lorentz ensemble are derived.
