Two-impurity Kondo problem for correlated electrons

arXiv:cond-mat/9702162 · doi:10.1103/PhysRevB.55.R8646

Abstract

The behavior of two magnetic impurities coupled to correlated electrons in one dimension is studied using the DMRG technique for several fillings. On-site Coulomb interactions among the electrons lead to a small Kondo screening cloud and an overall suppression of magnetic order. For arbitrary electronic correlations and large inter-impurity distances R, we find a 1/R^2 decay of magnetic correlations.
