Single-root multireference Brillouin-Wigner coupled-cluster theory. Rotational barrier of the ethylene molecule
Recently developed single-root multireference Brillouin-Wigner coupled cluster (MR BWCC) theory is applied to study the rotational barrier of the ethylene molecule. The method belongs to a broad family of state-selective

Size-extensivity Correction for the State-specific Multireference Brillouin-Wigner Coupled-cluster Theory.
We present a simple a posteriori correction for the state-specific multireference Brillouin-Wigner coupled-cluster theory, which eliminates its size-extensivity error....

On the generalized multi-reference Brillouin-Wigner coupled cluster theory
The generalized multireference Brillouin-Wigner coupled cluster theory is presented for the case of a single root function. The Bloch-like equation and the Lippmann-Schwinger-like equation for the generalized multireference...

Method of moments for the continuous transition between the Brillouin-Wigner-type and Rayleigh-Schroumldinger-type multireference coupled cluster theories
We apply the method of moments to the multireference (MR) coupled cluster (CC and Rayleigh-Schroumldinger-type theories based on the Jeziorski-Monkhorst wave function of the SUMRCC theory to the general model space...
