摘要：
We investigate the behavior of the four-terminal resistance R-4pt in an interacting quantum wire described by a Luttinger liquid with an applied bias voltage V and coupled to two voltage probes. We extend previous results, obtained for very weakly coupled contacts, to the case in which the effects of the probes become non-trivially correlated. (C) 2012 Elsevier B.V. All rights reserved.
