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…
Nonthermal electron-photon steady states in open cavity quantum materials
R. Flores-Calderón, Md Mursalin Islam, Michele Pini +1
Coupling a system to two different baths can lead to novel phenomena escaping the constraints of thermal equilibrium. In quantum materials inside optical cavities, this feature can…
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…
Evolution of an attractive polarized Fermi gas: From a Fermi liquid of polarons to a non-Fermi liquid at the Fulde-Ferrell-Larkin-Ovchinnikov quantum critical point
Michele Pini, Pierbiagio Pieri, Giancarlo Calvanese Strinati
The evolution of an attractive polarized two-component Fermi gas at zero temperature is analyzed as its polarization is progressively decreased, from full polarization (correspondi…
Strong Fulde-Ferrell Larkin-Ovchinnikov pairing fluctuations in polarized Fermi systems
M. Pini, P. Pieri, G. Calvanese Strinati
We calculate the pair susceptibility of an attractive spin-polarized Fermi gas in the normal phase, as a function of the pair momentum. Close to unitarity, we find a strong enhance…
Beyond-mean-field description of a trapped unitary Fermi gas with mass and population imbalance
M. Pini, P. Pieri, R. Grimm +1
A detailed description is given of the phase diagram for a two-component unitary Fermi gas with mass and population imbalance, for both homogeneous and trapped systems. This aims a…
Pair correlations in the normal phase of an attractive Fermi gas
M. Pini, P. Pieri, M. Jäger +2
In a recent paper [Phys. Rev. A 99, 053617 (2019)], the total number of fermion pairs in a spin-balanced two-component Fermi gas of Li atoms was experimentally probed in the no…
Fermi gas throughout the BCS-BEC crossover: Comparative study of t-matrix approaches with various degrees of self-consistency
M. Pini, P. Pieri, G. Calvanese Strinati
The diagrammatic t-matrix approximation has often been adopted to describe a dilute Fermi gas. This approximation, originally considered by Galitskii for a repulsive inter-particle…
Pair fraction in a finite temperature Fermi gas on the BEC side of the BCS-BEC crossover
Thomas Paintner, Daniel K. Hoffmann, Manuel Jäger +8
We investigate pairing in a strongly interacting two-component Fermi gas with positive scattering length. In this regime, pairing occurs at temperatures above the superfluid critic…
