We investigate Anderson localization in a quasi–one-dimensional
disordered system consisting of weakly coupled statistically
independent channels. The dependence of the localization length
on the coupling κ is shown to be singular: proportional to
. Numerical evidence is given for coupled random
chains with different statistics of site potential. An analytical
approach is developed based on the Fokker-Planck treatment of the
coupled stationary Schrödinger equations with Gaussian
delta-correlated potentials.
