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…

Fermionic Superfluidity: From Cold Atoms to Neutron Stars
Annette Lopez, Patrick Kelly, Kaelyn Dauer +1
From flow without dissipation of energy to the formation of vortices when placed within a rotating container, the superfluid state of matter has proven to be a very interesting phy…

Dynamical structure factor of a fermionic supersolid on an optical lattice
Ettore Vitali, Patrick Kelly, Annette Lopez +2
Interfacing unbiased quantum Monte Carlo simulations with state-of-art analytic continuation techniques, we obtain exact numerical results for dynamical density and spin correlatio…
