Coherent electron dynamics in a two-dimensional random system with mobility edges
F. A. B. F. de Moura, M. L. Lyra, F. Dominguez-Adame +1
We study numerically the dynamics of a one-electron wave packet in a two-dimensional random lattice with long-range correlated diagonal disorder in the presence of a uniform electr…
Anomalous optical absorption in a random system with scale-free disorder
E. Diaz, A. Rodriguez, F. Dominguez-Adame +1
We report on an anomalous behavior of the absorption spectrum in a one-dimensional lattice with long-range-correlated diagonal disorder with a power-like spectrum in the form S(k)…
Localization properties of a one-dimensional tight-binding model with non-random long-range inter-site interactions
F. A. B. F. de Moura, A. V. Malyshev, M. L. Lyra +2
We perform both analytical and numerical studies of the one-dimensional tight-binding Hamiltonian with stochastic uncorrelated on-site energies and non-fluctuating long-range hoppi…
Bloch oscillations in an aperiodic one-dimensional potential
F. A. B. F. de Moura, M. L. Lyra, F. Dominguez-Adame +1
We study the dynamics of an electron subjected to a static uniform electric field within a one-dimensional tight-binding model with a slowly varying aperiodic potential. The unbias…
Phase coherence in tight-binding models with nonrandom long-range hopping
D. B. Balagurov, V. A. Malyshev, F. Dominguez-Adame
The density of states, even for a perfectly ordered tight-binding model, can exhibit a tail-like feature at the top of the band, provided the hopping integral falls off in space sl…
Bloch-like oscillations in a one-dimensional lattice with long-range correlated disorder
F. Domínguez-Adame, V. A. Malyshev, F. A. B. F. de Moura +1
We study the dynamics of an electron subjected to a uniform electric field within a tight-binding model with long-range-correlated diagonal disorder. The random distribution of sit…
