Edge States and Their Transport in a Quantum Wire Exposed to a Non-Homogeneous Magnetic Field

Abstract

Edge states and their transport in a quantum wire exposed to a perpendicular non-homogeneous magnetic field are investigated. Systems are studied where the magnetic field exhibits a discontinuous jump in the transverse direction. The energy spectra and wave functions of these systems the corresponding group velocities along the interface and the particle average positions normal to the interface are calculated. The resistance of the quantum wire is obtained both in the ballistic and in the diffusive regimes as a function of the Fermi energy and of the homogeneous background magnetic field.
