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…

Control of electron-electron interaction in graphene by proximity screening
M. Kim, S. G. Xu, A. I. Berdyugin +14
Electron-electron interactions play a critical role in many condensed matter phenomena, and it is tempting to find a way to control them by changing the interactions' strength. One…
