摘要：

A maximum-entropy model describing the conductance statistics of disordered mesoscopic quantum wires is presented. The model, closely related to the Laguerre ensemble of random matrices, predicts a weak localization effect and universal conductance fluctuations, in qualitative agreement with microscopic theory. A simple interpretation of the maximum-entropy model is given and the relation with other maximum-entropy models is discussed.
