RANDOM-MATRIX MODELS WITH ADDITIONAL INTERACTIONS

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