Fermi Arcs in Anderson Lattice Models with <i>d</i>-wave Hybridization

ORAL

Abstract

We study an Anderson lattice model with a d-wave hybridization gap, using a second-order perturbation theory. Due to the interaction, the heavy electrons acquire a finite lifetime, while the light electrons do not. This asymmetric electron lifetime, combined with the momentum-dependent hybridization gap, results in Fermi arcs in electron’s spectrum function.
