Richardson-Gaudin mean-field for strong correlation in quantum chemistry
P. A. Johnson, C. -É. Fecteau, F. Berthiaume +8
Ground state eigenvectors of the reduced Bardeen-Cooper-Schrieffer Hamiltonian are employed as a wavefunction ansatz to model strong electron correlation in quantum chemistry. This…
Maximum Probability Domains for Hubbard Models
Guillaume Acke, Stijn De Baerdemacker, Pieter W. Claeys +4
The theory of Maximum Probability Domains (MPDs) is formulated for the Hubbard model in terms of projection operators and generating functions for both exact eigenstates as well as…
The density matrix renormalization group for ab initio quantum chemistry
Sebastian Wouters, Dimitri Van Neck
During the past 15 years, the density matrix renormalization group (DMRG) has become increasingly important for ab initio quantum chemistry. Its underlying wavefunction ansatz, the…
Exact Ionization Potentials from Wavefunction Asymptotics: The Extended Koopmans' Theorem, Revisited
Diederik Vanfleteren, Dimitri Van Neck, Paul W. Ayers +2
A simple explanation is given for the exactness of the extended Koopmans' theorem for computing the removal energy of any many-electron system to the lowest-energy ground state ion…
