Title: Evolution of Landau levels in graphene-based topological insulators in the presence of wedge disclinations

Abstract

In this paper we consider modification of electronic properties of graphene-based topological insulator in the presence of wedge disclination and magnetic field by adopting the Kane–Mele model with intrinsic spin–orbit coupling. Using the properly defined Dirac–Weyl equation for this system, an exact solution for the Landau levels is obtained. The influence of the topological defect on the evolution of Landau levels is discussed. - Highlights: • Landau levels in graphene-based topological insulator. • Graphene-based topological insulator in the presence of disclination. • Kane–Mele model in topological insulator with wedge disclination.
