Theory of one-dimensional double-barrier quantum pump in two-frequency signal regime
M. M. Mahmoodian, M. V. Entin
Abstract
A one-dimensional system with two δ-like barriers or wells bi-chromaticaly oscillating at frequencies ω and 2ω is considered. The alternating signal leads to the direct current across the structure (even in a symmetric system). The properties of this quantum pump are studied in a wide range of the system parameters.
