T-7

Goal: the goal of this set of problems is to derive an estimate for the transition point for the Anderson model on the Bethe lattice. Techniques: cavity method, stability analysis.

A criterion for localization

• Green functions and self-energies. Y .

- model on the be the lattice - self energy -criterion for localization - links to ergo breaking

Problem 7.1:

the cavity equation and the linearisation




Problem 7.2:
