Interplay between Kondo Effect and Randomness for Interacting Conduction Electrons

Quantum corrections to conductivity due to a paramagnetic impurity are examined for interacting electrons with randomness in the lowest order of the randomness parameter and in the third order of exchange interaction between the spin and electrons. The previous result for non-interacting electrons are enhanced by a factor η - d /2 , where η -1 is the Stoner enhancement factor and d is the dimensionality.
