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…
