Coupled cluster and perturbation theories based on a cluster mean-field reference applied to strongly correlated spin systems

no code implementations • 19 Feb 2021 • Athanasios Papastathopoulos-Katsaros, Carlos A. Jiménez-Hoyos, Thomas M. Henderson, Gustavo E. Scuseria

We introduce perturbation and coupled-cluster theories based on a cluster mean-field reference for describing the ground state of strongly-correlated spin systems.

Construction of linearly independent non-orthogonal AGP states

no code implementations • 22 Jan 2021 • Rishab Dutta, Guo P. Chen, Thomas M. Henderson, Gustavo E. Scuseria

We show how to construct a linearly independent set of antisymmetrized geminal power (AGP) states, which allows us to rewrite our recently introduced geminal replacement models as linear combinations of non-orthogonal AGPs.
