OverviewThe scientific missionThe INFM-CNR Research and Development Center on Bose-Einstein Condensation(BEC) is aimed to promote theoretical research on the various phenomena related toBose-Einstein condensation and to the physics of cold atomic gases. Since the firstobservation of BEC in cold gases in 1995, the study of ultracold gases has become anemerging area of research at the crossing point of several disciplines, including atomicand molecular physics, quantum optics, statistical mechanics and condensed matterphysics. BEC has been already achieved in many atomic species and an impressivenumber of experimental and theoretical groups worldwide is actively working in thefield of ultracold atomic gases.In the last years the field has further grown and developed in several importantdirections. On the one side the availability of advanced optical techniques has allowedto create new trapping configurations in the form of optical lattices. This has openednew frontiers of research where atomic physics meets important features of condensedmatter and solid state physics. These include the superfluid-Mott insulating transition,the implementation of new geometrical configurations where even the dimensionalityof the system can be controlled, the study of disorder and localization effects, theoccurrence of Bloch and Josephson oscillations, just to mention a few of them.The availability of Fano-Feshbach resonances characterizing the interaction betweenseveral atomic species has opened the fascinating possibility of tuning the two-bodyinteractions by simply changing the external magnetic field, with the consequence thatthe value and even the sign of the scattering length can be changed in controlledway, yielding the challenging and unique possibility of studying strongly correlatedconfigurations with dilute atomic gases. Important achievements concern the study ofultracold Fermi gases. The initial cooling limitations due to Pauli blocking have beenovercome and now the field of ultracold Fermi gases is growing in an impressive way5
