Current drag in capacitevly coupled Luttinger constrictions
Yuli V. Nazarov, D. V. Averin
Abstract
We study the current drag in the system of two electrostatically coupled finite 1D electron channels. We present the perturbation theory results along with the results for two non-perturbative regimes. It is shown that the drag may become absolute, that is, the currents in the channels are equal in a finite window of the bias voltages.
