Magnetic-flux-driven topological quantum phase transition and manipulation of perfect edge states in graphene tube
We study the tight-binding model for a graphene tube with perimeter N threaded by a magnetic field. We show exactly that this model has different nontrivial topological phases as the flux changes. The winding number, as an indicator of topological quantum phase transition (QPT) fixes at N/3 if N/3 e...
