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:
