  Title Quantized conductance without reservoirs : method of the nonequilibrium statistical operator Type A1 Journal article
  Year (down) 2007 Publication Journal of computational electronics Abbreviated Journal J Comput Electron  
  Volume 6 Issue 1/3 Pages 255-258  
  Keywords A1 Journal article; Condensed Matter Theory (CMT)  
  Abstract We introduce a generalized non-equilibrium statistical operator (NSO) to study a current-carrying system. The NSO is used to derive a set of quantum kinetic equations based on quantum mechanical balance equations. The quantum kinetic equations are solved self-consistently together with Poissons equation to solve a general transport problem. We show that these kinetic equations can be used to rederive the Landauer formula for the conductance of a quantum point contact, without any reference to reservoirs at different chemical potentials. Instead, energy dissipation is taken into account explicitly through the electron-phonon interaction. We find that both elastic and inelastic scattering are necessary to obtain the Landauer conductance.
