Abstract
We applied the recurrent variational approach to the two-leg Hubbard ladder . At half filling, our variational ansatz was a generalization of the reson ating valence-bond state. At finite doping, hole pairs were allowed to move in the resonating valence-bond background. The results obtained by the rec urrent variational approach were compared with results from density matrix renormalization group. [S0163-1829(99)00332-X].
