Kondo Destruction and Heavy Fermion Phase Diagram

This paper addresses a fundamental problem in condensed matter physics: understanding strange metals, using heavy fermion systems as a model. It offers a novel field-theoretic approach, analyzing the competition between the Kondo effect and local-moment magnetism from the magnetically ordered side. The significance lies in its ability to map out the global phase diagram and reveal a quantum critical point where the Kondo effect transitions from being destroyed to dominating, providing a deeper understanding of heavy fermion behavior.
