Delocalization in One-Dimensional Tight-Binding Models with Fractal Disorder

摘要

In the present work, we investigated the correlation-inducedlocalization-delocalization transition in the one-dimensional tight-bindingmodel with fractal disorder. We obtained a phase transition diagram fromlocalized to extended states based on the normalized localization length bycontrolling the correlation and the disorder strength of the potential. Inaddition, the transition of the diffusive property of wavepacket dynamics isshown around the critical point.
