Spin current and rectification in Luttinger liquids
Bernd Braunecker, D. E. Feldman, Feifei Li
We demonstrate that spin current can be generated by an ac voltage in a one-channel quantum wire with strong repulsive electron interactions in the presence of a non-magnetic impur…

Can backscattering off an impurity enhance the current?
D. E. Feldman, Yuval Gefen
It is well known that while forward scattering has no effect on the conductance of one-dimensional systems, backscattering off a static impurity suppresses the current. We study th…
