Realistic Theory of Strongly Correlated Systems linie570

Emergent phenomena occurr in systems in which the electron-electron repulsion is large. Understanding these phenomena is one of the central issues in solid state physics. The rich variety of emergent behaviors is the result of the interplay between Coulomb repulsion orbital, spin, charge degrees of freedom and chemistry. We are interested in understanding this interplay.
