Overcoming the detrimental effect of disorder at nanoscale is very hard since induces localization and an exponential suppression transport efficiency. Here we unveil novel robust quantum regimes achievable in nanosystems by exploiting long-range hopping. We demonstrate that a 1D disordered nanostructure presence hopping, efficiency, after decreasing exponentially with first, then enhanced [disorder-enhanced (DET) regime] until, counterintuitively, it reaches disorder-independent (DIT)...
Static disorder in a 3D crystal degrades the ideal ballistic dynamics until it produces localized regime.This Metal-Insulator Transition is often preceded by coherent diffusion.By studying three paradigmatic 1D models, namely Harper-Hofstadter-Aubry-André and Fibonacci tight-binding chains, along with power-banded random matrix model, we show that whenever diffusion present, transport exceptionally stable against decoherent noise.This completely at odds what happens for coherently dynamics,...
