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

Abstract

The Kondo lattice model enlarged by an antiferromagnetic coupling $J_{\mathrm{AF}}$ 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 $J_{\mathrm{AF}}$=0.
