    Boson Gas in a Periodic Array of Tubes

    We report the thermodynamic properties of an ideal boson gas confined in an infinite periodic array of channels modeled by two, mutually perpendicular, Kronig-Penney delta-potentials. The particle’s motion is ...

    Bose-Einstein Condensation in Multilayers

    The critical BEC temperature T c of a non interacting boson gas in a layered structure like those of cuprate superconductors is shown to have a minimum

    Low-dimensional BEC

    The Bose-Einstein condensation (BEC) temperature Tc of Cooper pairs (CPs) created from a general interfermion interaction is determined for a linear, as well as the usually assumed quadratic, energy vs center-of-...
