Phys. Rev. Lett. 89, 226404 (2002) [4 pages]Landauer-Type Transport Theory for Interacting Quantum Wires: Application to Carbon Nanotube Y JunctionsReceived 9 July 2002; published 8 November 2002 We propose a Landauerlike theory for nonlinear transport in networks of one-dimensional interacting quantum wires (Luttinger liquids). A concrete example of current experimental focus is given by carbon nanotube Y junctions. Our theory has three basic ingredients that allow one to explicitly solve this transport problem: (i) radiative boundary conditions to describe the coupling to external leads, (ii) the Kirchhoff node rule describing charge conservation, and (iii) density matching conditions at every node. © 2002 The American Physical Society URL:
