We investigate the anomalous behavior of localization length of a non-interacting one-
dimensional Anderson model at zero temperature. We report numerical calculations of the …

We consider a one-dimensional simple random walk killed by quenched soft obstacles. The
position of the obstacles is drawn according to a renewal process with a power-law …

We study numerically the localization properties of eigenstates in a one-dimensional
random lattice described by a non-Hermitian disordered Hamiltonian, where both the …

We consider the one-dimensional Anderson model with weak disorder. Using the
Hamiltonian map approach, we analyse the validity of the random-phase approximation for …

We consider two bidimensional random models characterised by the following features:(a)
their Hamiltonians are separable in polar coordinates and (b) the random part of the …

We study the band-center anomaly in the one-dimensional Anderson model with the
disorder characterized by short-range positive correlations. Using the Hamiltonian map …
