A variational Jastrow coupled-cluster theory of quantum many-body systems
Y. Xian
We study many-body correlations in the ground states of a general quantum system of bosons or fermions by including an additional Jastrow function in our ecently proposed variation…

Excited states of quantum many-body interacting systems: A variational coupled-cluster description
Y. Xian
We extend recently proposed variational coupled-cluster method to describe excitation states of quantum many-body interacting systems. We discuss, in general terms, both quasiparti…
