  It has been argued that despite remarkable success, existing random matrix
theories are not adequate to describe disordered conductors in the metallic
regime, due to the presence of certain two-body interactions in the effective
Hamiltonian for the eigenvalues, in addition to the standard logarithmic
interaction that arises entirely from symmetry considerations. We present a new
method that allows exact solution of random matrix models with such additional
two-body interactions. This should broaden the scope of random matrix models in
general.
