Cluster Operator Formalism

Cluster Operator Formalism is a theoretical framework in quantum chemistry that employs an exponential ansatz of excitation operators to systematically construct wavefunctions for many-electron systems within Coupled Cluster Theory, distinguishing itself by ensuring size-extensivity and non-variational accuracy through connected-cluster expansions.
