Modelling of materials with strongly correlated electrons

Topics:

• The discovery of high-Tc materials in the mid eighties has prompted a spectacular improvement of the experimental techniques in material science. As an outcome, new materials are being synthesized with unexpected magnetic and electric properties that are challenging the traditional understanding in condensed matter physics and that call for new theoretical methods and ideas. Quantum field theory methods are finding application in these new subjects. We are in particular interested in the following topics:

  • Renormalization Group approach to electron systems.

  • Correlated electrons in low dimensions.

  • Quantum phase transitions. Metal-Insulator transitions.

  • Gauge theories in condensed matter systems.

  • Graphite and related materials: fullerenes, nanotubes, nanofoam.
