Four-body correlation embedded in antisymmetrized geminal power wave function

Airi Kawasaki, Osamu Sugino (arXiv:1609.01438, The Journal of Chemical Physics 145, 244110 (2016))

In this paper, the authors extend the conventional two-body geminal wave functions to include the four-body correlations. By using HΦ, they examine the accuracy of the extended geminal wave functions up to 20 site Hubbard model.
