On the connectivity criteria in the open-shell coupled-cluster theory for general model spaces
TLDR
In this article, the authors study the open-shell coupled-cluster theories and examine the current theoretical status regarding the existence or non-existence of a linked-clusters theorem, ensuring the connectedness of the cluster amplitudes and the effective Hamiltonian.About:

Coupled-cluster theory in quantum chemistry
Rodney J. Bartlett,Monika Musiał +1 more
TL;DR: In this article, the essential aspects of coupled-cluster theory are explained and illustrated with informative numerical results, showing that the theory offers the most accurate results among the practical ab initio electronic-structure theories applicable to moderate-sized molecules.

Equation of motion coupled cluster method for electron attachment
TL;DR: The electron attachment equation of motion coupled cluster (EA•EOMCC) method is derived in this paper, which enables determination of the various bound states of an (N+1)-electron system and the corresponding energy eigenvalues relative to the energy of an N•electron CCSD reference state.

Many-Body Perturbation Theory and Coupled Cluster Theory for Electron Correlation in Molecules
TL;DR: Manybody perturbation theory (MBPT) and coupled-cluster methcoder (CCM) were defined in this paper as a subset of the N-body problem.

Electron correlation theories and their application to the study of simple reaction potential surfaces
TL;DR: In this article, an implementation of the coupled cluster theory with double substitutions (CCD) was described, and the authors applied this method and closely related fourth-order perturbation methods to some simple molecules and reaction potential surfaces.

Cluster expansion of the wavefunction. Excited states
TL;DR: In this paper, a method for excited states is given on the basis of the symmetry-adapted-cluster (SAC) expansion method, based on the fact that the SAC expansion method gives incidentally a set of excited functions which satisfies the Brillouin theorem with the ground state.
