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…
