Electronic transport through a correlated quantum wire connected to a
superconducting lead    [PDF]

P. P. Aseev, S. N. Artemenko

We study theoretically the electron transport in a 1D conductor adiabatically connected to a superconducting and normal metal leads. In the case of non-interacting electrons in the wire, we obtain full I-V curve. We show that ac voltage applied along with dc voltage modifies I-V curve resembling a regime of photon-assisted tunneling. We obtain in the limit of low voltages, that the electron-electron interaction affects electronic transport resulting in a decrease of conductance and features in the frequency dependence of the impedance.
