Ground States of Heisenberg Spin Clusters from Projected Hartree-Fock Theory
Shadan Ghassemi Tabrizi, Carlos A. Jiménez-Hoyos
We apply Projected Hartree-Fock theory (PHF) for approximating ground states of Heisenberg spin clusters. Spin-rotational, point-group and complex-conjugation symmetry are variatio…

Coupled cluster and perturbation theories based on a cluster mean-field reference applied to strongly correlated spin systems
Athanasios Papastathopoulos-Katsaros, Carlos A. Jiménez-Hoyos, Thomas M. Henderson +1
We introduce perturbation and coupled-cluster theories based on a cluster mean-field reference for describing the ground state of strongly-correlated spin systems. In cluster mean-…
