I’m working on several aspects of the problem of strongly correlated electronic systems, with current emphasis on frustrated magnetism and low-dimensional conductors, in the context of several transition metal oxides as well as organic conductors and carbon nanotubes. The problems addressed are always of experimental relevance, and I’m collaborating with experimental chemistry and physics teams all over the world, in particular in France and Japan. The general goal is to find new phases of matter at low temperature coming from strong correlations. Recent successes include the explanation of the structure of the 1/8 magnetization plateau of SrCu2(BO3 )2, a Mott insulator with strong magnetic frustration. Current efforts are devoted to the identification of true spin liquids with topological degeneracy in Mott insulators with magnetic frustration and/or orbital degeneracy.
