2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/215861We discuss various superfluid properties of a two-component Fermi system in the presence of a tight one-dimensional periodic potential in a three-dimensional system. We use a zero temperature mean field theory and derive analytical expressions for the Josephson current, the sound velocity and the center of mass oscillations in the BCS-Bose Einstein condensation crossover region.6 pages, 5 figures, Updated with the published versionOther Condensed Mattertext
