Robust d-wave Pairing Correlations in the Heisenberg Kondo Lattice Model

Strongly Correlated Electrons 2009-11-13 v1 Superconductivity

Abstract

The Kondo lattice model enlarged by an antiferromagnetic coupling JAFJ_{\rm AF} between the localized spins is here investigated using computational techniques. Our results suggest the existence of a d-wave superconducting phase close to half-filling mediated by antiferromagnetic fluctuations. This establishes a closer connection between theory and heavy fermion experiments than currently provided by the standard Kondo lattice model with JAFJ_{\rm AF}=0.
