N-electron Slater determinants from non-unitary canonical transformations of fermion operators
Carlos A. Jimenez-Hoyos, R. Rodriguez-Guzman, Gustavo E. Scuseria
Mean-field methods such as Hartree-Fock (HF) or Hartree-Fock-Bogoliubov (HFB) constitute the building blocks upon which more elaborate many-body theories are based on. The HF and H…
Symmetry-projected variational approach for ground and excited states of the two-dimensional Hubbard model
R. Rodríguez-Guzmán, K. W. Schmid, Carlos A. Jiménez-Hoyos +1
We present a symmetry-projected configuration mixing scheme to describe ground and excited states, with well defined quantum numbers, of the two-dimensional Hubbard model with near…
Projected Hartree-Fock Theory
Carlos A. Jimenez-Hoyos, Thomas M. Henderson, Takashi Tsuchimochi +1
Projected Hartree-Fock theory (PHF) has a long history in quantum chemistry. PHF is here understood as the variational determination of an N-electron broken symmetry Slater determi…
