摘要：

A perturbative study of the localization length in the Anderson model on strips is presented. It is shown that in the neighbourhood of those energies corresponding to the opening of a new channel, a certain rearrangement of the perturbation expansion significantly improves the accuracy of the prediction. Moreover, the localization length scales in a way which is reminiscent of the strictly 1D behaviour, but is nevertheless different.
