Multireference Electron Correlation Methods: Journeys along Potential Energy Surfaces [PDF]
Chemical Reviews, 2020 Multireference electron correlation methods describe static and dynamical electron correlation in a balanced way, and therefore, can yield accurate and predictive results even when single-reference methods or multiconfigurational self-consistent field (MCSCF) theory fails. One of their most prominent applications in quantum chemistry is the exploration

Variational Methods for Atoms and the Virial Theorem
Atoms, 2022 In the case of the one-electron Dirac equation with a point nucleus, the virial theorem (VT) states that the ratio of the kinetic energy to potential energy is exactly −1, a ratio that can be an independent test of the accuracy of a computed solution ...
