Title: A Ginzburg-Landau-type model of carbon nanotubes

Abstract: I will demonstrate that a multiwalled carbon nanotube - an interacting system of concentric carbon layers - can be effectively described by a Ginzburg-Landau-type energy with a potential that has multiple wells. The number of wells depends on the geometric characteristics of the tube and leads to the experimentally observed polygonization effect
