This lecture covers the Coupled Cluster theory, focusing on the expansion of the perturbed wavefunction in doubly excited Slater determinants and the second-order correction to the energy. It discusses Size Extensivity and Size Consistency, post-Hartree-Fock methods like Configuration Interaction and Coupled Cluster Theory, and why truncated Configuration Interaction is not size-consistent.
