The effect of Coulomb interactions on the ac mobility of charges in quasi-one-dimensional systems. Example: Discotic liquid crystals

Using Monte Carlo simulations we calculate the frequency dependence of the diffusive mobility of a group of carriers on a short one-dimensional chain. We allow the carriers to interact with each other through weakly screened long-range Coulomb potentials. We consider both doped systems with discrete immobile counterions and gated systems with...
