Research area

Theoretical studies of strongly correlated electrons (or quantum materials) focusing mostly on models for high-temperature superconductors and layered organic superconductors.

Quantum Materials

Properties of high-temperature superconductors and layered organic superconductors cannot be explained by conventional theoretical approaches, despite the fact that these approaches have had spectacular sucesses. These successes are visible today in particular in modern electronics, that was built on the detailed fundamental understanding of semiconductors, metals and magnetic materials.

The conceptual and methodological challenges of high-temperature superconductor extends to many other classes of materials that have in common a very large anisotropy (one- or two-dimensional), the presence of strong interactions between electrons and the importance of collective quantum phenomena. These materials are collectively known as quantum materials. In addition to superconductivity, they can exhibit other spectacular and technologically useful properties such as unusually large thermopower, magnetoresistance, magnetocaloric effects etc...

Ongoing Research

  • Calculations of specific properties and mechanisms of strongly correlated superconductivity, including high-temperature superconductors, organic superconductors and other forms of non-conventional superconductivity using cluster generalizations of dynamical mean field theory.
  • Development of new methodology for strongly correlated electrons: Quantum Impurity solvers, Two-particle Self-Consistent Approach, inhomogeneous systems such as heterostructures...
