Abstract

The Kondo effect of the Anderson impurity in a correlated conduction electron system is studied with the slave boson mean-field theory. The interacting conduction electrons are described by a Hubbard model with an interaction of strength U. It is shown that the Kondo temperature T K decreases with an increase of U. In the intermediate regime at half-filling, the exponential scale of the Kondo temperature T K is already lost at the saddle-point level of slave boson formulation.
