In this work, we consider the motion of a polaron in a polynucleotide
Holstein molecular chain in a constant electric field. It is shown that the
character of the polaron motion in the chain depends not only on the chosen
parameters of the chain, but also on the initial distribution of the charge
along the chain. It is shown that for a small set value of the electric field
intensity and for fixed values of the chain parameters, changing only the
initial distribution of the charge in the chain, it is possible to observe
either a uniform movement of the charge along the chain, or an oscillatory mode
of charge movement.
