Near-exact treatment of seniority-zero ground and excited states with a Richardson-Gaudin mean-field
Charles-Émile Fecteau, Samuel Cloutier, Jean-David Moisset +4
Eigenvectors of the reduced Bardeen-Cooper-Schrieffer Hamiltonian, Richardson-Gaudin (RG) states, are used as a variational wavefunction Ansatz for strongly-correlated electronic s…
Transition density matrices of Richardson-Gaudin states
Paul A. Johnson, Hubert Fortin, Samuel Cloutier +1
Recently, ground state eigenvectors of the reduced Bardeen-Cooper-Schrieffer Hamiltonian, Richardson-Gaudin (RG) states, have been employed as a wavefunction ansatz for strong corr…
Reduced density matrices of Richardson-Gaudin states in the Gaudin algebra basis
Charles-Émile Fecteau, Hubert Fortin, Samuel Cloutier +1
Eigenvectors of the reduced Bardeen-Cooper-Schrieffer Hamiltonian have recently been employed as a variational wavefunction ansatz in quantum chemistry. This wavefunction is a mean…
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…
