Presentation Transcript

  1. Trapped ultracold atoms: Bosons Bose-Einstein condensation of a dilute bosonic gas Probe of superfluidity: vortices

  2. Ultracold bosons in an optical lattice A double well Increasing V, one passes from a superfluid to a Mott insulator

  3. Trapped ultracold atoms: Fermions A non-interacting Fermi gas Tuning the interactions… … and inducing a fermionic “condensate”

  4. Probing the superfluidity for fermionic gases Close to the crossover … … and in a lattice

  5. More on the BCS-BEC crossover

  6. Trapped ultracold atoms Ultracold bosons and/or fermions in trapping potentials provide new experimentally realizable interacting systems on which to test well-known paradigms of the statistical mechanics: -) in a periodic potential -> strongly interacting lattice systems -) interaction can be enhanced/tuned through Feshbach resonances (BEC-BCS crossover – unitary limit) -) inhomogeneity can be tailored – defects/impurities can be added -) effects of the nonlinear interactions on the dynamics -) strong analogies with superconducting and superfluid systems -) quantum coherence / superfluidity on a mesoscopic scale -) quantum vs finite temperature physics -) needed a theory for mesoscopic open systems …
