Ghosh, T. K., De Martino, A., Häusler, W. , Dell'Anna, L. & Egger, R. (2008). Conductance quantization and snake states in graphene magnetic waveguides. Physical Review B (PRB), 77(8), article number 081404. doi: 10.1103/physrevb.77.081404
Abstract
We consider electron waveguides (quantum wires) in graphene created by suitable inhomogeneous magnetic fields. The properties of uni-directional snake states are discussed. For a certain magnetic field profile, two spatially separated counter-propagating snake states are formed, leading to conductance quantization insensitive to backscattering by impurities or irregularities of the magnetic field.
