Spectrum of density, spin and pairing fluctuations of an attractive two-dimensional Fermi gas
Christian Apostoli, Patrick Kelly, Annette Lopez +4
We leverage random phase approximation and unbiased auxiliary-field quantum Monte Carlo methods to compute dynamical correlations for a dilute homogeneous two-dimensional attractiv…
Quantum Monte Carlo and perturbative study of two-dimensional Bose-Fermi mixtures
Jacopo D'Alberto, Lorenzo Cardarelli, Davide Emilio Galli +2
We derive analytically the leading beyond-mean field contributions to the zero-temperature equation of state and to the fermionic quasi-particle residue and effective mass of a dil…
Quantum Monte Carlo study of the role of p-wave interactions in ultracold repulsive Fermi gases
Gianluca Bertaina, Marco G. Tarallo, Sebastiano Pilati
Single-component ultracold atomic Fermi gases are usually described using noninteracting many-fermion models. However, recent experiments reached a regime where -wave interactio…
Toward precision Fermi liquid theory in two dimensions
Silas R. Beane, Gianluca Bertaina, Roland C. Farrell +1
The ultra-cold and weakly-coupled Fermi gas in two spatial dimensions is studied in an effective field theory framework. It has long been observed that universal corrections to the…
Evolution of static and dynamical density correlations in a one-dimensional soft-core gas from the Tonks-Girardeau limit to a clustering fluid
Martina Teruzzi, Christian Apostoli, Davide Pini +2
Repulsive soft-core atomic systems may undergo clustering if their density is high enough that core overlap is unavoidable. In one-dimensional quantum systems, it has been shown th…
Quantum Monte Carlo simulations of two-dimensional repulsive Fermi gases with population imbalance
S. Pilati, G. Orso, G. Bertaina
The ground-state properties of two-component repulsive Fermi gases in two dimensions are investigated by means of fixed-node diffusion Monte Carlo simulations. The energy per parti…
