Inclusion of pairing fluctuations in a semiclassical approach: The case of study of the Josephson effect
Verdiana Piselli, Leonardo Pisani, Giancarlo Calvanese Strinati
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 tak…
Tunneling spectra of unconventional quasi-two-dimensional superconductors
L. Pisani, A. G. Moshe, P. Pieri +2
Superfluid condensation can fundamentally be different from that predicted by the Bardeen-Cooper-Schrieffer (BCS) theory. In a broad class of low-carrier-density superconductors, s…
Josephson current flowing through a nontrivial geometry: The role of pairing fluctuations across the BCS-BEC crossover
Verdiana Piselli, Leonardo Pisani, Giancarlo Calvanese Strinati
A realistic description of the Josephson effect at finite temperature with ultra-cold Fermi gases embedded in nontrivial geometrical constraints (typically, a trap plus a barrier)…
Critical current throughout the BCS-BEC crossover with the inclusion of pairing fluctuations
Leonardo Pisani, Verdiana Piselli, Giancarlo Calvanese Strinati
The present work aims at providing a systematic analysis of the current density versus momentum characteristics for a fermionic superfluid throughout the BCS-BEC crossover, even in…
