Workshop on Strong Electron Correlations in Quantum Materials: Inhomogeneities, Frustration, and Topology

The last decades have seen much progress in the field of Condensed Matter Physics, driven primarily by the experimental discovery of a number of novel materials displaying exotic behavior such as unconventional superconductivity, fractional statistics, and topologically nontrivial phases. It has become clear that many of these interesting properties arise from strong interactions between their constituent electrons, with growing evidence of the key role played by inhomogeneities, frustration and topological aspects of the matter.

This area of Strongly Correlated Electronic systems has become one of the most interesting, active, and intellectually challenging fields in Condensed Matter Physics. In this workshop, we bring together experts working on this challenging and rapidly evolving field, to present their experimental and theoretical progress. This will allow for a vigorous exchange of ideas and the possibility to start exciting new collaborations between the participants. There is no registration fee.
