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…
Mass-imbalanced two-dimensional Bose-Fermi mixtures with boson-fermion pairing
Cristiano Luigi Kosman Chiarappa, Pietro Bovini, Pierbiagio Pieri
We analyze a two-dimensional Bose-Fermi mixture at zero temperature in the presence of a tunable Bose-Fermi attraction. We adopt a diagrammatic T-matrix approach and study the beha…
Band-minimum degeneracy is not enough: density-of-states control of low-density ferromagnetism
Jinghao Wang, Pierbiagio Pieri
Recent ultracold-atom experiments have observed ferromagnetic correlations in a geometrically tunable Fermi--Hubbard lattice at intermediate densities. Motivated by subsequent theo…
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…
Mutual friction and vortex Hall angle in a strongly interacting Fermi superfluid
Nicola Grani, Diego Hernández-Rajkov, Cyprien Daix +8
The motion of a quantized vortex is intimately connected with its microscopic structure and the elementary excitations of the surrounding fluid. In this work, we investigate the tw…
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…
