Non-perturbative linked-cluster expansions in long-range ordered quantum systems
D. Ixert, K. P. Schmidt
We introduce a generic scheme to perform non-perturbative linked cluster expansions in long-range ordered quantum phases. Clusters are considered to be surrounded by an ordered ref…

Mott physics in the half-filled Hubbard model on a family of vortex-full square lattices
D. Ixert, F. F. Assaad, K. P. Schmidt
We study the half-filled Hubbard model on a one-parameter family of vortex-full square lattices ranging from the isotropic case to weakly coupled Hubbard dimers. The ground-state p…
