Negative longitudinal resistance of monolayer graphene in the quantum Hall regime

In the quantum Hall regime the charge current is carried by ideal one-dimensional edge channels where the backscattering is prohibited by topology. This results in the constant potential along the edge of the Hall bar leading to zero 4-terminal longitudinal resistance r_xx. Finite scattering between...
