摘要：

We show that the plateau transitions in the quantum Hall effect are the same as the dimerization transition of a half-filled one-dimensional U(2n) Hubbard model at n = 0. We address the properties of the latter by a combination of perturbative renormalization group and Monte Carlo simulations. Results on both critical and off-critical properties are presented.
