New electronic states of matter

The existence of strong correlations between electrons induces novel and unexpected states in solids, such as high temperature superconductivity, charge or spin orderings, quantum hall effects or spin liquids. A central activity in Laboratoire de Physique des Solides is devoted to studies of these novel states, both from an experimental and a theoretical point of vue.
