Proper and improper zero energy modes in Hartree-Fock theory and their relevance for symmetry breaking and restoration
Yao Cui, Ireneusz W. Bulik, Carlos A. Jimenez-Hoyos +2
We study the spectra of the molecular orbital Hessian (stability matrix) and random-phase approximation Hamiltonian of broken-symmetry Hartree-Fock solutions, focusing on zero eige…
Excited electronic states from a variational approach based on symmetry-projected Hartree--Fock configurations
Carlos A. Jiménez-Hoyos, R. Rodríguez-Guzmán, Gustavo E. Scuseria
Recent work from our research group has demonstrated that symmetry-projected Hartree--Fock (HF) methods provide a compact representation of molecular ground state wavefunctions bas…
Multi-component symmetry-projected approach for molecular ground state correlations
Carlos A. Jiménez-Hoyos, R. Rodríguez-Guzmán, Gustavo E. Scuseria
The symmetry-projected Hartree--Fock ansatz for the electronic structure problem can efficiently account for static correlation in molecules, yet it is often unable to describe dyn…
