FREQUENCY DEPENDENCES IN TRANSPORT THROUGH A TOMONAGA-LUTTINGER LIQUID WIRE

Dynamics of one-dimensional electron transport between two reservoirs are studied based on the inhomogeneous Tomonaga-Luttinger-liquid model in the case when the effect of the electron backscattering on the impurities is negligible. The inhomogeneities of the interaction lead to a charge-wave reflection. This effect supposes a special behavior of the transport characteristics at the microwave frequencies. Different features are predicted in the current noise spectrum and in the ac frequency dependence. \textcopyright{} 1996 The American Physical Society.
