Dataset for "Non-Perturbative Feats in the Physics of Correlated Antiferromagnets"

The preprint and LaTeX source files are available on arXiv . The dataset contains paramagnetic and antiferromagnetic (AF) results from dynamical mean-field theory calculations of the two-dimensional Hubbard model at the one- and the two-particle level.

The study investigates divergences of the two-particle irreducible vertex function in the coupled charge and spin sectors within the AF phase. The data map the location of these divergences across the AF phase diagram, showing how AF order reduces but does not eliminate the breakdown of the self-consistent perturbation expansion. Additionally, the results capture the changes in the dynamical structure of the corresponding generalized susceptibilities linking them to the crossover from a weak-coupling (Slater) to a strong-coupling (Heisenberg) antiferromagnet and explore potential links to phase-separation instabilities.
