| Zusammenfassung | The generalization of the Dorokhov-Mello-Pereyra-Kumar equation for the description of transport in strongly disordered systems replaces the symmetry parameter β by a new parameter γ, which decreases to zero when the disorder strength increases. We show numerically that although the value of γ strongly influences the statistical properties of transport parameters Δ and of the energy level statistics, the form of their distributions always depends on the symmetry parameter β even in the limit of strong disorder. In particular, the probability distribution is p(Δ) ~ Δβ when Δ→0 and p(Δ) ~ exp(-cΔ2) in the limit Δ→∞. |
