Ferromagnetic spin correlations in the two-dimensional Hubbard model
We analyze the dynamical nearest-neighbor and next-nearest-neighbor spin correlations in the four-site and eight-site dynamical cluster approximation to the two-dimensional Hubbard model. Focusing on the robustness of these correlations at long imaginary times, we reveal enhanced ferromagnetic corre...
