Landauer transport as a quasisteady state on finite chains under unitary quantum dynamics
J. P. Santos Pires, B. Amorim, J. M. Viana Parente Lopes
In this paper, we study the emergence of a Landauer transport regime from the quantum-mechanical dynamics of free electrons in a disordered tight-binding chain, which is coupled to…

Global Delocalization Transition in the de Moura-Lyra Model
J. P. Santos Pires, N. A. Khan, J. M. Viana Parente Lopes +1
The possibility of having a delocalization transition in the 1D de Moura-Lyra class of models (having a power-spectrum has been the object of a long standing disc…

Spectral Functions of One-Dimensional Systems with Correlated Disorder
N. A. Khan, J. M. Viana Parente Lopes, J. P. Santos Pires +1
We investigate the spectral function of Bloch states in an one-dimensional tight-binding non-interacting chain with two different models of static correlated disorder, at zero temp…
