Dynamical correlation within the Interacting Quantum Atoms method through coupled cluster theory

Correlation in IQA through CC theory. HF-CC transition densities are used to obtain first order reduced density matrices and pair densities that are consistent with closed shell coupled cluster energies. By these means, dynamical electron correlation is included in the Interacting Quantum Atoms partition of the electronic energy. We anticipate that the developments presented in this paper will prove useful in the study of systems and processes in chemistry wherein electron correlation plays an important role.
