Magnetism trends in doped Ce-Cu intermetallics in the vicinity of quantum criticality: Realistic Kondo lattice models based on dynamical mean-field theory

Abstract

The quantum critical point (QCP) in the archetypical heavy-fermion compound CeCu6 doped by Au is described, accounting for the localized 4f electron of Ce, using realistic electronic structure calculations combined with dynamical mean-field theory. Magnetism trends in Ce(Cu1-ϵAuϵ)6 (0
