Query: Tuning equilibration of quantum Hall edge states in graphene - role of
  crossed electric and magnetic fields   We probe quantum Hall effect in a tunable 1-D lateral superlattice (SL) in
graphene created using electrostatic gates. Lack of equilibration is observed
along edge states formed by electrostatic gates inside the superlattice. We
create strong local electric field at the interface of regions of different
charge densities. Crossed electric and magnetic fields modify the wavefunction
of the Landau Levels (LLs) - a phenomenon unique to graphene. In the region of
copropagating electrons and holes at the interface, the electric field is high
enough to modify the Landau levels resulting in increased scattering that tunes
equilibration of edge states and this results in large longitudinal resistance.
