Evolution of the electronic structure of CeCoIn5 across a quantum critical point

ORAL

Abstract

The existence and nature of a possible quantum critical point in CeCoIn5 have been under debate for many years. Recent work has focused on the details of f-c hybridization in the evolution of the Kondo lattice as a function of temperature. Here we report a doping- and temperature-dependent study of CeCoIn5 by angle-resolved photoemission spectroscopy. Changes to the electronic structure with both doping and temperature, as well as the possible existence of a quantum critical point, are discussed.
