FFLO transition and quantum criticality in polarized Fermi gases
Francesco Pirolo, Leonardo Pisani, Pierbiagio Pieri
The paper studies the zero‑temperature transition from a polarized normal phase to the FFLO state in two‑dimensional Fermi gases, introduces a self‑consistent t‑matrix approach tha…
Stability of Bose-Fermi mixtures in two dimensions: a lowest-order constrained variational approach
Pietro Cordioli, Leonardo Pisani, Pierbiagio Pieri
We investigate the problem of mechanical stability in two-dimensional Bose-Fermi mixtures at zero temperature, focusing on systems with a tunable Bose-Fermi (BF) interaction and a…
Density Modulations of Zero Sound
Leonardo Pisani
We study the density modulation of an interacting Fermi gas caused by the uniform motion of an impurity at zero temperature. For strong enough interaction among Fermi atoms, the mo…
Mechanical stability of resonant Bose-Fermi mixtures
Christian Gualerzi, Leonardo Pisani, Pierbiagio Pieri
We investigate the mechanical stability of Bose-Fermi mixtures at zero temperature in the presence of a tunable Feshbach resonance, which induces a competition between boson conden…
Boson-fermion pairing and condensation in two-dimensional Bose-Fermi mixtures
Leonardo Pisani, Pietro Bovini, Fabrizio Pavan +1
We consider a mixture of bosons and spin-polarized fermions in two dimensions at zero temperature with a tunable Bose-Fermi attraction. By adopting a diagrammatic T-matrix approach…
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…
