Scattering approach to current and noise in interacting mesoscopic systems
arXiv:cond-mat/0703546 · doi:10.1103/PhysRevB.76.125309
Abstract
We propose an extension of the Landauer-Buttiker scattering theory to include effects of interaction in the active region of a mesoscopic conductor structure. The current expression obtained coincides with those derived by different methods. A new general expression for the noise is also established. These expressions are then discussed in the case of strongly sequential tunneling through a double-barrier resonant tunneling structure.
