Inclusion of pairing fluctuations in a semiclassical approach: The case of study of the Josephson effect
arXiv:2410.04382 · doi:10.1140/epja/s10050-024-01258-x
Abstract
Recent refinements on a semiclassical approach are reviewed, aiming at describing the inhomogeneous local gap parameter in the presence of non-trivial spatial geometries and at taking into account at the same time pairing fluctuations beyond mean field. The method is applied to describe the Josephson effect over the wide range of physical conditions related to recent experiments on this topic performed with ultra-cold Fermi gases.
