Recurrent Variational Approach to the Two-Leg Hubbard Ladder
arXiv:cond-mat/9902107 · doi:10.1103/PhysRevB.60.5169
Abstract
We applied the Recurrent Variational Approach to the two-leg Hubbard ladder. At half-filling, our variational Ansatz was a generalization of the resonating valence bond state. At finite doping, hole pairs were allowed to move in the resonating valence bond background. The results obtained by the Recurrent Variational Approach were compared with results from Density Matrix Renormalization Group.
