Voltage profile and four-terminal resistance of an interacting quantum wire
We investigate the behavior of the four-terminal resistance R<sub>4pt</sub> in a quantum wire described by a Luttinger liquid in two relevant situations: (i) in the presence of a single impurity within the wire and (ii) under the effect of asymmetries introduced by disordered voltage pro...

| description |
We investigate the behavior of the four-terminal resistance R<sub>4pt</sub> in a quantum wire described by a Luttinger liquid in two relevant situations: (i) in the presence of a single impurity within the wire and (ii) under the effect of asymmetries introduced by disordered voltage probes. In the first case, interactions leave a signature in a power-law behavior of R<sub>4pt</sub> as a function of the voltage V and the temperature T. In the second case interactions tend to mask the effect of the asymmetries. In both scenarios the occurrence of negative values of R<sub>4pt</sub> is explained in simple terms. |
