Charge Motion along a Polynucleotide Chains in a Constant Electric Field Depends on the Charge Coupling Constant with Chain Displacements

Various regimes of a charge motion along chain in constant electric field are investigated. This is simulated on the basis Holstein model. Earlier studies demonstrate possibility uniform over very long distances. For small values intensity polaron can move at velocity. As increases, acquires oscillatorily character, performing Bloch oscillations. Since depends whole set system parameters character not only value intensity. Therefore, for which takes place differs chains with different parameters. The and distribution considered coupling between displacements chain. It shown that regime changes constant. also demonstrated one same intensity, either or an oscillatory motion, stationary be observed.
