NGF Method for Transport Through Nanosystems
In this chapter the quantum transport technique of the nonequilibrium many-body theory is described. A model is introduced for discrete-level Hamiltonian, tunneling coupling to ideal electrodes, electron-electron interaction, linear vibrons and the linear electron-vibron interaction. The Dyson-Keldysh equations for nanosystems in integral and differential forms and the Meir-Wingreen-Jauho current formula are described.
