Variational description of the ground state of the repulsive two-dimensional Hubbard model in terms of nonorthogonal symmetry-projected Slater determinants
R. Rodríguez-Guzmán, Carlos A. Jiménez-Hoyos, Gustavo E. Scuseria
The few determinant (FED) methodology, introduced in our previous works for 1D lattices, is here adapted for the repulsive two-dimensional Hubbard model at half-filling and with fi…
Multi-reference symmetry-projected variational approximation for the ground state of the doped one-dimensional Hubbard model
R. Rodríguez-Guzmán, Carlos A. Jiménez-Hoyos, Gustavo E. Scuseria
A multi-reference configuration mixing scheme is used to describe the ground state, characterized by well defined spin and space group symmetry quantum numbers as well as doping fr…
Symmetry-projected Wave Functions in Quantum Monte Carlo Calculations
Hao Shi, Carlos A. Jiménez-Hoyos, R. Rodríguez-Guzmán +2
We consider symmetry-projected Hartree--Fock trial wave functions in constrained-path Monte Carlo (CPMC) calculations. Previous CPMC calculations have mostly employed Hartree--Fock…
