The Anderson transition: New numerical results for the critical exponents

The results of our recent evaluation of the critical exponents of the localization length, v and the conductivity, s, at the Anderson transition for box and Gaussian distributions of the random potential are reported. Data are evaluated not only in the centre of the band but also near the band edge. Near the band centre we obtain s = v = 1.4±0.2, and s = v = 0.9±0.3 for the box and the Gaussian distribution, respectively. Near the band edge we found it impossible to determine accurately the exponents.
