We report the application of the density-matrix renormalization-group method to a spatially anisotropic two-dimensional Hubbard model at half filling. We find a deconfinement transition induced by the transverse hopping parameter ty from an insulator to a metal. Therefore, if ty is fixed in the metallic phase, increasing the interaction U leads to a metal-to-insulator transition at a finite critical U. This is in contrast to the weak-coupling Hartree-Fock theory which predicts a nesting-induced antiferromagnetic insulator for any U>0.
