After reviewing recent progress in the area of the development of coupled-cluster (CC)
methods for quasi-degenerate electronic states that are characterized by stronger non …

The full and active-space doubly electron-attached (DEA) and doubly ionized (DIP) equation-
of-motion coupled-cluster (EOMCC) methods with up to 4-particle–2-hole (4p-2h) and 4-hole …

We have recently suggested the CC (P; Q) methodology that can correct energies obtained
in the active-space coupled-cluster (CC) or equation-of-motion (EOM) CC calculations …

We have recently proposed the CC (P; Q) methodology that provides a systematic approach
to correcting the energies obtained in active-space coupled-cluster (CC) calculations for the …

We have recently developed a flexible form of the method of moments of coupled-cluster
(CC) equations and the CC (P; Q) hierarchy, which enable one to correct the CC and …

We recently proposed a novel approach to converging electronic energies equivalent to
high-level coupled-cluster (CC) computations by combining the deterministic CC (P; Q) …

We recently proposed a semi-stochastic approach to converging high-level coupled-cluster
(CC) energetics, such as those obtained in the CC calculations with singles, doubles, and …

Adaptation of improved virtual orbitals (IVOs) in state‐specific multireference perturbation
theory using Møller–Plesset multipartitioning of the Hamiltonian (IVO‐SSMRPT) is examined …

We have recently developed the full and active-space doubly electron-attached (DEA) and
doubly ionised (DIP) equation-of-motion coupled-cluster (EOMCC) methods with up to 4 …

Here we review the basic formalism, implementation details, and performance of two newly
developed coupled cluster (CC) methods based on the unrestricted Hartree–Fock (UHF) …
