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…
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…
Identifying Band Inversions in Topological Materials Using Diffusion Monte Carlo
Annette Lopez, Cody A. Melton, Jeonghwan Ahn +2
Topological insulators are characterized by insulating bulk states and robust metallic surface states. Band inversion is a hallmark of topological insulators: at time-reversal inva…
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…
Gaussian Processes for Finite Size Extrapolation of Many-Body Simulations
Edgar Josué Landinez Borda, Kenneth O. Berard, Annette Lopez +1
Key to being able to accurately model the properties of realistic materials is being able to predict their properties in the thermodynamic limit. Nevertheless, because most many-bo…
