Entanglement coupled cluster theory: Exact spin-adaptation
Presents a new spin-adapted Coupled Cluster framework. Unpaired electrons are entangled with electrons in bath orbitals that do not interact with the molecular system of interest. Desired spin symmetries are obtained with projection operators.
Particle-Breaking Unrestricted Hartree–Fock Theory for Open Molecular Systems
A wave function that considers interactions with an environment resulting in a linear combination of states with different numbers of electrons. It generalizes the restricted model, which is important for a realistic description of fractional charging.
