Abstract: We study a lattice sigma model which is expected to reflect the Anderson localization/delocalization transition for real symmetric band matrices in 3d. For this model we prove localization at high temperatures for any dimension $d\geq 1$ and the existence of a diffusive phase in 3 dimensions at low temperature (joint work with T. Spencer and M. Zirnbauer).
