Divergent density of states and non-analytic Lyapunov exponent in one-dimensional slowly varying systems
Hai-Tao Hu, Ming Gong, Guangcan Guo +1
Localization of wave functions in disordered systems can be characterized by the Lyapunov exponent, which is zero in the extended phase and nonzero in the localized phase. Previous…

Exact mobility edges in quasiperiodic network models with slowly varying potentials
Hai-Tao Hu, Yang Chen, Xiaoshui Lin +3
Quasiperiodic models are important physical platforms to explore Anderson transitions in low dimensional systems, yet the exact mobility edges (MEs) are generally hard to be determ…

Hidden self-duality and exact mobility edges in quasiperiodic network models
Hai-Tao Hu, Xiaoshui Lin, Ai-Min Guo +3
In one-dimensional quasiperiodic systems, only a few models with exact mobility edges (MEs) have been constructed using generalized self-duality theory, Avila's global theory, or t…
