Figure 2 Objective: To extend the simple model from Lectures 1 into the full-fledged Non-equilibrium Green’s Function (NEGF) – Landauer model by introducing a spatial grid of N points and turning numbers like into (NxN) matrices like , with incoherent scattering introduced through . This model will be used to provide a quantitative description of key experiments such as the conductance of point contacts and the quantum Hall effect and also to introduce key concepts like transverse modes, spectral functions and density matrices.

This lecture is part 2 of 2.
