摘要：

We examine the effect of interchain hopping on the quasi-one-dimensional Hubbard model at half filling. Treating interactions within the weak-coupling perturbation theory, we derive two-loop renormalization-group equations for vertices and self energies. It is shown that the Mott gap is suppressed for weak interchain hopping, while it is enhanced for strong interchain hopping.
