摘要：
We consider electron waveguides (quantum wires) in graphene created by suitable inhomogeneous magnetic fields. The properties of unidirectional snake states are discussed. For a certain magnetic field profile, two spatially separated counterpropagating snake states are formed, leading to conductance quantization insensitive to backscattering by impurities or irregularities of the magnetic field.
