Universality classes for Coulomb frustrated phase separation

TL;DR

This paper classifies two universality classes in Coulomb frustrated phase separation, linking them to electronic compressibility anomalies in strongly correlated systems, and compares their phase diagrams across dimensions.

Contribution

It introduces a classification of universality classes for Coulomb frustrated phase separation based on electronic compressibility anomalies.

Findings

Two universality classes identified for Coulomb frustrated phase separation.

Differences and similarities in phase diagrams across 2D and 3D systems.

Connection between universality classes and electronic compressibility anomalies.

Abstract

We identify two "universality" classes in the Coulomb frustrated phase separation phenomenon. They correspond to two different kind of electronic compressibility anomalies often encountered in strongly correlated electronic systems. We discuss differences and similarities of their corresponding phase diagrams in two- and three-dimensional systems.
