Abstract
Examining electron current dl backscattered inside a 1D wire connected to l eads, we have found that at low energy some physical quantities are renorma lized by the interaction inside the wire, while some are not. (1) The charg e of the average current and of its zero frequency fluctuations are not ren ormalized. (2) The charge and spin susceptibilities are renormalized. Testi ng the latter with transport experiment is suggested. (C) 1999 Elsevier Sci ence Ltd. All rights reserved.
