AbstractWe study theoretically the alternating current (ac) transport property through a two-channel clean quantum wire of finite length in the presence of both inter-channel and intra-channel electron-electron (e-e) interactions. Using the bosonization technique and linear response theory, we have obtained analytical expressions of the ac conductance. Interestingly, the ac conductance oscillations, with two different frequencies, form a beat which governs the behavior of the transport property in the presence of inter-channel e-e interaction. This result provides us with a new way to control the transport property of narrow quantum wires by engineering the Fermi velocities in the two different channels, i.e., the electron density.
