Influence of broken-pair excitations on the exact pair wavefunction
Jacob M. Wahlen-Strothman, Thomas M. Henderson, Gustavo E. Scuseria
Doubly occupied configuration interaction (DOCI), the exact diagonalization of the Hamiltonian in the paired (seniority zero) sector of the Hilbert space, is a combinatorial cost w…
Merging symmetry projection methods with coupled cluster theory: Lessons from the Lipkin model Hamiltonian
Jacob M Wahlen-Strothman, Thomas M. Henderson, Matthew R. Hermes +5
Coupled cluster and symmetry projected Hartree-Fock are two central paradigms in electronic structure theory. However, they are very different. Single reference coupled cluster is…
Biorthogonal projected energies of a Gutzwiller similarity transformed Hamiltonian
Jacob M. Wahlen-Strothman, Gustavo E. Scuseria
We present a method incorporating biorthogonal orbital-optimization, symmetry projection, and double-occupancy screening with a non-unitary similarity transformation generated by t…
