Modeling of stationary and nonstationary regimes of charge transfer in a homogeneous Holstein chain in a constant electric field
Numerical simulation of charge transfer in a Holstein molecular chain in a constant electric field was carried out. It is shown that for selected chain parameters, there is the possibility of uniform charge transfer in a constant electric field over very long distances, to hundreds of thousands of sites. The movement of a charge with a constant velocity is possible for small values of the electric field intensity. At increasing the value of the electric field intensity, the moving of charge transforms into an oscillatory mode of motion with Bloch oscillations. A good agreement between the theoretical and numerical dependence of the uniform charge velocity on the electric field intensity is shown.
