摘要：

The directed network model describing chiral edge states on the surface of a cylindrical three-dimensional quantum Hall system is known to map to a one-dimensional (1D) quantum ferromagnetic spin chain. Using the spin-wave expansion for this chain, we determine the universal functions for the crossovers between the two-dimensional chiral metallic and 1D metallic regimes in the mean and variance of the conductance along the cylinder, to first nontrivial order.
