    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

    Thoughts about Anomalous Diffusion: Time-Dependent Coefficients versus Memory Functions

    Electrons and holes in a semiconducting device [1], interstitial atoms injected into a solid [2], molecules in a gas container, ink droplets in a glass of liquid, mice carrying the deadly Hantavirus over a lan...

    Harmonically trapped ideal quantum gases

    We solve the problem of a Bose or Fermi gas in d-dimensions trapped by δ ⩽ d mutually perpendicular harmonic oscillator potentials. From the grand potential we derive their thermodynamic functions (internal energ...

    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-...
