Propagation of acoustic edge waves in graphene under quantum Hall effect
We consider a graphene sheet with a zigzag edge subject to a perpendicular magnetic field and investigate the propagation of in-plane acoustic edge waves. In particular it is shown that propagation is significantly blocked for certain frequencies defined by the resonant absorption due to electronic-...
