Quasi-Diffusion in a 3D SUSY Hyperbolic Sigma Model

Spencer, T (Princeton)
Monday 15 December 2008, 10:00-11:00

Seminar Room 1, Newton Institute


We analyze a SUSY lattice field model which qualitatively reflects Anderson localization and delocalization. Correlations in this model may be described in terms of a random walk in a highly correlated random environment. We prove this model exhibits a "diffusive" phase in 3 or more dimensions. This is joint work with M. Disertori and M. Zirnbauer.
