The non-equilibrium Greens function (NEGF) formalism provides a powerful conceptual and computational framework for treating quantum transport in nanodevices. It goes beyond the Landauer approach for ballistic, non-interacting electronics to include inelastic scattering and strong correlation effects at an atomistic level.
Check out Supriyo Datta's NEGF page for more information, or browse through the various resources listed below.

A short overview of this series of four lectures is given.
CQT Lecture 1: Nanodevices and Maxwell's Demon
Objective: To illustrate the subtle interplay of
dynamics and thermodynamicsthat distinguishes transport physics.
CQT Lecture 2: Electrical Resistance - A Simple Model
To introduce a simple quantitative
model for describing current flow in nanoscalestructures and relate it to
well-known large scale properties like Ohm’s Law.
CQT Lecture 3: Probabilities, Wavefunctions and Green Functions
Objective: To extend the simple model from Lecture 2
into the full-blown model combines the NEGF (Non-Equilibrium
Green Function) method with the Landauer approach.
CQT Lecture 4: Coulomb blockade and Fock space
To illustrate the limitations of the model
described in Lectures 2, 3 and introduce a completely different approach based on
the concept of Fock space.
I believe this will be a...
