We obtain the transition temperature in the strongly correlated regime, as well as temperature dependence of energy, entropy, double occupancy, and the nearest-neighbor spin correlation function. Our results improve the accuracy of previous unbiased studies and present accurate benchmarks in the ongoing effort to realize the antiferromagnetic state of matter with ultracold atoms in optical lattices.14 pagesIn CopyrightPhysics, Condensed MatterPhysicsOPTICAL LATTICEINFINITE DIMENSIONSGROUND-STATESYSTEMSINSULATORPHYSICSATOMSNeel temperature and thermodynamics of the half-filled three-dimensional Hubbard model by diagrammatic determinant Monte CarloArticle - RefereedPhysical Review Bhttps://doi.org/10.1103/PhysRevB.87.2051028720Scarola, VW [0000-0002-8653-2723]
