FFLO transition and quantum criticality in polarized Fermi gases
Francesco Pirolo, Leonardo Pisani, Pierbiagio Pieri
We investigate the zero-temperature transition from the polarized normal phase to the FFLO state in a two-dimensional Fermi gas by means of a diagrammatic t-matrix approach. We fir…
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…
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…
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…
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…
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…
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…
Peaks and widths of radio-frequency spectra: An analysis of the phase diagram of ultra-cold Fermi gases
L. Pisani, M. Pini, P. Pieri +1
We provide a comprehensive theoretical study of the radio-frequency (rf) spectra of a two-component Fermi gas with balanced populations in the normal region of the temperature-vs-c…
