Range of the Kondo Cloud in Weakly Disordered Hosts

Abstract

The calculation of the Kondo cloud is extended to disordered hosts. For a weakly disordered large three-dimensional host the structure of the ground state is very close to the pure host. However, the range of the disordered electron basis is much shorter. The extention of the Kondo cloud is essentially given by √ ξ K l where ξ K is the Kondo length in the pure host and l the mean free path.
