论文摘要
在本章中，我们对石墨烯扭结和抗树林的建模中获得的主要结果进行了回顾，这些结果是弯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 - 安替克散射和辐射键相互作用。我们还报告了一些新发现，包括i）证据表明，石墨烯扭结的动能是通过相对论表达来描述的，ii）证明了在纵向方向压缩的膜中扭结动态的阻尼动力学。特别关注的是，在经典标量$ ϕ^4 $理论中，石墨烯扭结和扭结之间的相似性和差异。本章讨论的石墨烯扭结的独特特性可能会在纳米级运动中找到应用。
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.
