Long-range ballistic transport of Brown-Zak fermions in graphene superlattices
Julien Barrier, Piranavan Kumaravadivel, Roshan Krishna-Kumar +16
In quantizing magnetic fields, graphene superlattices exhibit a complex fractal spectrum often referred to as the Hofstadter butterfly. It can be viewed as a collection of Landau l…
