Multifractality and anomalous diffusion at the mobility edge in disordered systems

Autor: Ludwig Schweitzer, B. Huckestein

Publikováno v: Journal of Non-Crystalline Solids. :461-464

The properties of electronic wave functions in disordered systems have been investigated for 1-, 2- and 3- dimensional tight binding models with diagonal disorder. It is shown that the multifractal nature of the eigenstates at a mobility edge influen

The properties of the states near the centres of the Landau bands in disordered two-dimensional systems are investigated with respect to their asymptotic and fractal behaviour. It is shown that they can be described by a one-parameter scaling law clo

Current-voltage characteristics and the zero-resistance state in a two-dimensional electron gas

Publikováno v: Physical Review B. 67

We study the current-voltage characteristics (CVC) of two-dimensional electron gases with microwave-induced negative conductance in a magnetic field. We show that due to the Hall effect, strictly speaking, there is no distinction between N- and S-sha

Localization and Scaling in the Quantum Hall Regime: Dependence on Landau Level Index and Correlation Length

Autor: B. Kramer, B. Huckestein

Publikováno v: Springer Series in Solid-State Sciences ISBN: 9783642844102

The exponential decay length λ M of the one-particle Greens function is calculated for a disordered two-dimensional system of finite width M under the influence of a strong magnetic field. A recursive numerical method is employed. The influence of t
