Kondo Destruction and Heavy Fermion Phase Diagram

Published:Dec 31, 2025 18:33
1 min read
ArXiv

Analysis

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.
Reference

“The paper reveals a quantum critical point across which the Kondo effect goes from being destroyed to dominating.”

Sub-Ensemble Correlations as a Covariance Geometry

Published:Dec 30, 2025 20:14
1 min read
ArXiv

Analysis

This paper challenges the conventional assumption of independence in spatially resolved detection within diffusion-coupled thermal atomic vapors. It introduces a field-theoretic framework where sub-ensemble correlations are governed by a global spin-fluctuation field's spatiotemporal covariance. This leads to a new understanding of statistical independence and a limit on the number of distinguishable sub-ensembles, with implications for multi-channel atomic magnetometry and other diffusion-coupled stochastic fields.
Reference

“Sub-ensemble correlations are determined by the covariance operator, inducing a natural geometry in which statistical independence corresponds to orthogonality of the measurement functionals.”
