  Using a local moment approach of Logan et al. we developed a solver for a
multi-orbital single impurity Anderson model. The existence of the local
moments is taken from the outset and their values are determined through
variational principle by minimizing the corresponding ground state energy. The
method is used to solve the dynamical mean-field equations for the
multi-orbital Hubbard model. In particular, the Mott-Hubbard metal--insulator
transition is addressed within this approach.
