Effective eigenstates in a dynamical disordered tight-binding model

We study effective eigenstates—in mean value—for a 1D tight-binding (TB) Hamiltonian in the presence of diagonal dynamical disorder (DD). The averaged density of states (DOS) and localization length are shown as a function of the intensity of disorder and the correlation time of its temporal fluctuations. A delocalization electronic phenomenon is interpreted in terms of the localization length of the wave function, as a function of the time correlation of the DD.
