摘要:

在本章中,我们综述了在石墨烯扭结和反扭结建模方面取得的主要结果,它们是屈曲石墨烯膜的基本拓扑激发。我们介绍了扭结的分类,并讨论了扭结—反扭结散射以及辐射—扭结相互作用。我们还报告了一些新发现,包括:i)有证据表明石墨烯扭结的动能可由一个相对论性表达式描述;ii)演示了在纵向压缩膜中扭结的阻尼动力学。本章特别关注突出石墨烯扭结与经典标量 $ϕ^4$ 理论中扭结之间的异同。本章讨论的石墨烯扭结的独特性质可能在纳米尺度运动中获得应用。

英文摘要:

In this Chapter we provide a review of the main results obtained in the modeling of graphene kinks and antikinks, which are elementary topological excitations of buckled graphene membranes. We introduce the classification of kinks, as well as discuss kink-antikink scattering, and radiation-kink interaction. We also report some new findings including i) the evidence that the kinetic energy of graphene kinks is described by a relativistic expression, and ii) demonstration of damped dynamics of kinks in membranes compressed in the longitudinal direction. Special attention is paid to highlight the similarities and differences between the graphene kinks and kinks in the classical scalar $ϕ^4$ theory. The unique properties of graphene kinks discussed in this Chapter may find applications in nanoscale motion.
