摘要：

We have applied newly numerical schemes to study the ground-state properties of the 1D Hubbard model. Through finite-size scaling, we determine the singularity of the momentum distribution at kF and the power law decay of the spin and charge correlations in real space. Our results confirm the non-Fermi-liquid nature of the system. The model is shown to scale to the Tomonaga-Luttinger model even in the large4 regime where perturbative results are invalid. © 1990 IOP Publishing Ltd.
