Query: A Jastrow factor coupled cluster theory for weak and strong electron
  correlation   We present a Jastrow-factor-inspired variant of coupled cluster theory that
accurately describes both weak and strong electron correlation. Compatibility
with quantum Monte Carlo allows for variational energy evaluations and an
antisymmetric geminal power reference, two features not present in traditional
coupled cluster that facilitate a nearly exact description of the strong
electron correlations in minimal-basis N2 bond breaking. In double-zeta
treatments of the HF and H2O bond dissociations, where both weak and strong
correlations are important, this polynomial cost method proves more accurate
than either traditional coupled cluster or complete active space perturbation
theory. These preliminary successes suggest a deep connection between the ways
in which cluster operators and Jastrow factors encode correlation.
