摘要:

我们证明了碳纳米管(CNTs)中的长时间共振能量交换的径向呼吸模式作为载体的新的具体现象。该过程在较宽的激发能范围内是稳定的。结果表明,修正的非线性薛定谔方程,得到的非线性弹性薄壳理论的框架内,描述的CNT的非线性动力学在所考虑的频带。薄壳理论方程的数值积分证实了解析研究的结果。

英文摘要:

We demonstrate the new specific phenomenon of the long-time resonant energy exchange in the carbon nanotubes (CNTs) with the radial breathing mode as a carrier. This process turns out to be stable in the wide range of the excitation energy. It is shown that the modified nonlinear Schrödinger equation, obtained in the framework of nonlinear elastic thin shell theory, describes the CNT nonlinear dynamics in the considered frequency band. The numerical integration of the thin shell theory equations confirms the results of the analytical study.
