Dynamical structure factor of a fermionic supersolid on an optical lattice
Dynamical structure factor of a fermionic supersolid on an optical lattice
Interfacing unbiased quantum Monte Carlo simulations with state-of-art analytic continuation techniques, we obtain exact numerical results for dynamical density and spin correlations in the attractive Hubbard model, describing a spin-balanced two-dimensional cold Fermi gas on an optical lattice. We focus on half-filling, where on average one fermion occupies each lattice …
