D.C. Transport Measurements and the Direction of Propagation of Composite Fermion Edge States
Abstract
Description
Simple and quite general considerations are used to show that the results of d.c. transport experiments on macroscopic Hall bars are inconsistent with Hartree models in which a majority of the branches of single-particle composite fermion edge states at the Fermi level propagate in the direction opposite to that in which non-interacting electrons travel along the edge.
