摘要：

We investigate the influence of electron-phonon interactions on the de conductance Gamma of a quantum wire in the limit of one occupied subband. At zero temperature, a Tomonaga-Luttinger-like renormalization of Gamma to a value slightly larger than 2e(2)/h is calculated for a realistic quantum wire model.
