Universality classes for Coulomb frustrated phase separation

We identify two “universality” classes in the Coulomb frustrated phase separation phenomenon. They correspond to two different kinds of electronic compressibility anomalies often encountered in strongly correlated electronic systems. We discuss differences and similarities of their corresponding pha...

Description
Summary:We identify two “universality” classes in the Coulomb frustrated phase separation phenomenon. They correspond to two different kinds 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.
