Abstract

Numerical experiments based on the Peyrard–Bishop–Holstein model have been conducted to demonstrate the possibility of charge transfer by polarons in the homogeneous Poly G/Poly C-chain of DNA subjected to a constant electric field. It has been shown that a polaron in this model can travel large distances along the chain with a constant velocity if the electric field is weak. The charge motion ceases to be uniform with an increase in field strength: the charge starts executing Bloch oscillations.

根据Peyrard–Bishop–Holstein模型,在恒定电场作用下,均质Poly G / Poly C链中极化子的电荷转移

摘要

已经进行了基于Peyrard-Bishop-Holstein模型的数值实验,以证明极化子在恒定电场作用下DNA的均质Poly G / Poly C链中极化子转移电荷的可能性。已经证明,如果电场弱,该模型中的极化子可以以恒定的速度沿链条传播很长的距离。随着场强的增加,电荷运动不再是均匀的:电荷开始执行布洛赫振荡。
