The scaled-invariant Planckian metal and quantum criticality in Ce1−x Nd x CoIn5

Abstract

The Planckian metal is a special case of a strange metal, in which the linear-in-temperature scattering rate reaches a universal limit. Here the authors study this state in a heavy-fermion superconductor in magnetic field and propose a microscopic mechanical based on quantum criticality of the Kondo hybridization.
