报告摘要：Graphene, a single atomic layer of carbon atoms arranged in a honeycomb lattice, is a unique two-dimensional system with a vanishing effective mass for both the electrons and holes near the Fermi level. Many interesting physical properties of graphene have been identified and investigated within the framework of massless relativistic fermions. When one stacks the graphene layers on top of each other, modification of the physical properties may occur in an unexpected way. In this talk, I will discuss our computational efforts that investigate the special electronic properties of twisted few-layer graphene, such as Fermi velocity renormalization and the fractal features of the Landau levels in twisted bilayer.
