Dynamics in chains randomly doped with nonadiabatic impurities
Dynamics_in_chains.pdf (369.7Kb)Abstract
We study propagation of excitations in one-dimensional tight-binding chains doped with random impurities that are classical Einstein oscillators. We find that the presence of impurities does not affect substantially the masses, wave propagation is faster than that of the ordered tight-binding chain
