摘要:

研究了在低温和外加电场作用下,交变电磁场在锯齿形碳纳米管系统中的传播。碳纳米管的电子系统进行了研究微观nonmetering与声子子系统的相互作用的事实,电磁脉冲是临界短。得到了交变电磁场矢势振幅的有效方程。导出了电子子系统中与余弦色散关系下的孤子相对应的孤子类似物的解。分析了所获得的非线性解对问题参数和外加电场的依赖关系。证明了在宽范围内控制光脉冲形状的可能性。

英文摘要:

Propagation of the alternating electromagnetic field in a system of zigzag carbon nanotubes in the case of low temperatures and applied external electric fields are considered. The electronic system of the carbon nanotubes is investigated microscopically nonmetering an interaction with a phonon subsystem by the fact that the electromagnetic pulse is critically short. An efficient equation for the vector-potential amplitude of the alternating electromagnetic field is obtained. Solutions of solitons analogs which correspond to solitons in the case of cosine dispersion law for the electronic subsystem have been elicited. The dependences of obtained nonlinear solutions on problem parameters and the applied external electric fields were analyzed. The possibility to control the shape of optical pulse in wide range was shown.
