摘要: 对于有电场存在下的反式聚乙炔单链中的孤子运动,用SSH模型引入电场项,通过数值计算,对孤子在电场下的运动规律进行了模拟.得到孤子在电场下沿链匀速运动的结论.

关键词: 聚乙炔, 孤子, SSH模型

Abstract: Soliton dynamics is simulated for trans-polyacetylene single-chain systems using the Su-Schrieffer-Heeger (SSH) model with an additional part to include an external electric field. It is shown that the soliton moves along the chain with a constant speed when an external electric field is applied.

Key words: polyacetylene, soliton, SSH model
