Influences of an impurity on the transport properties of one-dimensional antisymmetric spin filter
arXiv:0710.3088 · doi:10.1103/PhysRevB.76.195319
Abstract
The influences of an impurity on the spin and the charge transport of one-dimensional antisymmetric spin filter are investigated using bosonization and Keldysh formulation and the results are highlighted against those of spinful Luttinger liquids. Due to the dependence of the electron spin orientation on wave number the spin transport is not affected by the impurity, while the charge transport is essentially identical with that of spinless one-dimensional Luttinger liquid.
