Bivariational Principle for an Antisymmetrized Product of Nonorthogonal Geminals Appropriate for Strong Electron Correlation
Paul A. Johnson, Paul W. Ayers, Stijn De Baerdemacker +2
We develop a bivariational principle for an antisymmetric product of nonorthogonal geminals. Special cases reduce to the antisymmetric product of strongly-orthogonal geminals (APSG…
The seniority quantum number in Tensor Network States
Klaas Gunst, Dimitri Van Neck, Peter A. Limacher +1
We employ tensor network methods for the study of the seniority quantum number - defined as the number of unpaired electrons in a many-body wave function - in molecular systems. Se…
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…
