"Transverse" persistent currents in mesoscopic cylinders and rings

Abstract

Persistent current is a nondecaying current in a normal metal ring or cylinder induced by the vector potential applied parallel to the direction of the current (longitudinal, or Aharonov-Bohm persistent current). A magnetic field applied perpendicular to the wall of the hollow metallic cylinder also produces an azimuthal nondecaying current (a transverse persistent current) even in the absence of the Aharonov-Bohm flux. Magnetic moment of a single connected conductor (a 2d conducting stripe) is supported by a current (a Landau-persistent current) which is shown to oscillate in space. © 2000 Published by Elsevier Science B.V.
