We investigate the three-dimensional Anderson model of localization via a modified transfer-matrix method in the presence of scale-free diagonal disorder characterized by a disorder correlation function $g(r)$ decaying asymptotically as $r^{-\alpha}$. We study the dependence of the localization-length exponent $\nu$ on the correlation-strength exponent $\alpha$. % For fixed disorder $W$, there is a critical $\alpha_{\rm c}$, such that for $\alpha<\alpha_{\rm c}$, $\nu=2/\alpha$ and for $\alpha… 
Resolution of the exponent puzzle for the Anderson transition in doped semiconductors
The Anderson metal-insulator transition (MIT) is central to our understanding of the quantum mechanical nature of disordered materials. Despite extensive efforts by theory and experiment, there is
Wannier-Stark ladder in the linear absorption of a random system with scale-free disorder
We study numerically the linear optical response of a quasiparticle moving on a one-dimensional disordered lattice in the presence of a linear bias. The random site potential is assumed to be
Electronic transport in DNA.
TLDR
It is found that random and lambda-DNA have localization lengths allowing for electron motion among a few dozen basepairs only, and a novel enhancement of localization lengths is observed at particular energies for an increasing binary backbone disorder.
The interplay of mutations and electronic properties in disease-related genes
TLDR
By analysing 162 disease-related genes from a variety of medical databases with a total of almost 20,000 observed pathogenic mutations, a significant difference in the electronic properties of the population of observed mutations is shown compared to the set of all possible mutations.
