Multiple-Lump Waves and Their Breaking Properties for a Thermophoretic Motion System in a Graphene Sheet

A thermophoretic motion system with a variable heat transmission factor is investigated, which describes wrinkling soliton propagation in a substrate-supported graphene sheet. Analytic multiple-lump wave solutions are constructed via the Hirota bilinear method and symbolic computation. A numerical simulation shows that the system exhibits breaking lump waves. The system parameters control the open width and number of breaking gaps. These results should contribute to a better understanding of the propagation characteristics of wrinkling solitons in a complex graphene thermophoretic motion system.
