Here, we provide a four-band short-range tight-binding model whose two lower bands have the same topology, symmetry, and flatness as those of the twisted bilayer graphene and which can be used as an effective low-energy model.
WebGraphene nanoribbons (GNRs) ... The origin of topology in GNRs is the quantization of the Berry phase. 1 The Berry phase in a 1D system is calculated by integrating the Berry connection across the first Brillouin zone. If the 1D system has spatial symmetry (e.g., inversion or mirror) then the Berry phase is constrained to be either 0 or π. ...

WebSo in this chapter we will take graphene and make it into a topological system with chiral edge states. Graphene is a single layer of carbon atoms arranged in a honeycomb lattice. It is a triangular lattice with two atoms per unit cell, type \(A\) and type \(B\) , represented by red and blue sites in the figure:
