Research Activity:
He has started his research activity by studying the problem of quark confinement in lattice Quantum Chromodynamics; his research interests then shifted on condensed matter physics, focusing initially on stronglycorrelated magnetic systems and then on superconductivity and superfluidity. His current research activity focuses on the BCSBEC crossover and related problems in ultracold Fermi atoms, and on the properties of stronglyinteracting BoseFermi mixtures.
