Coupled-cluster Approximation

Coupled-Cluster Approximation is a systematic quantum mechanical method for approximating the solution to the Schrödinger equation within many-body perturbation theory, distinguished by its exponential ansatz for the wave operator that ensures size extensivity and high accuracy in describing electron correlation effects.
