摘要：

We study electron transport through a multi-mode quantum wire with small localized potential inhomogeneities in the framework of a microscopic approach. We find that due to electromagnetic fluctuations the conductance per mode decreases below the universal value 2e(2)/h although it remains finite. Simultaneously, the I-V characteristic of the wire shows nonlinearity. Both effects manifest a coexistence of elastic and inelastic channels of electron transport. Quantitatively, the electromagnetic fluctuations can be characterized by an effective impedance which shows a quadratic dispersion at low frequencies,Re Z(eff)(omega) proportional to omega(2).
