Correlated Electron Systems
Electrons confined within a material always interact through Coulomb's law. Sometimes this interaction is especially strong and the quantum wave function of the material develops correlations. When this happens, electrons can no longer be treated independently of each other. Strongly correlated electron systems give rise to some of the most interesting topics in quantum materials science, including high-temperature superconductivity, the fractional quantum Hall effect, quantum spin liquids, and the Kondo effect. Exploration of the emergent properties of correlated electron system is one of our primary goals.
