The XXIVth International Symposium on the Jahn-Teller Effect

The symposium addresses experimental observation, theoretical modeling, and computer simulation of physical and chemical phenomena associated with strongly correlated electronic and nuclear motions. The strong vibronic coupling of the Jahn-Teller and pseudo Jahn-Teller effects influences a variety of molecular and solid state properties including spectroscopy, photochemistry, ferroelectricity and multiferroicity, charge and energy transport, superconductivity, molecular magnetism and a number of other fields. The conference is designed as a multidisciplinary meeting of physicists, chemists, and material scientists with experimental, computational, or theoretical backgrounds in this field. Organized by topics and given by key researchers, invited talks will provide a panoramic view of the current and most important problems in this field.

Begun in 1976, these symposia have historically focused on the coupling between electronic and nuclear motions in molecules and solids under conditions of electronic degeneracy and pseudodegeneracy, when the Jahn-Teller and Pseudo Jahn-Teller effects are operative. More recently, the scope has expanded into a broader range of strong vibronic and electron-phonon couplings that influence a vast range of physical and chemical phenomena. This symposium intends to further enrich this field by involving novel modeling concepts, and to benefit from insight gained by its interdisciplinary nature.

Topics of the symposium:

  • Theory of electron-vibrational coupling in molecules and solids, including the Jahn-Teller and pseudo Jahn-Teller effects, both at the fundamental and computational level.
  • Vibronic coupling in molecules and clusters, fullerenes and fullerides, graphene, silicene, and other two-dimensional systems.
  • Conical intersections and dynamics on intersecting potential energy surfaces.
  • Energy and charge transport: excitonic and polaronic phenomena in molecules and solids.
  • Electron-phonon and electron-lattice interactions in solids: ferroelectrics, multiferroics, topological insulators, superconductors and impurity centers.
  • Further applications of electron-vibrational coupling in materials science: electronics, spintronics, photonics, molecular magnets, skyrmions.
  • Vibronic coupling in transition-metal complexes: spin-states, spin-crossover, etc.
