Feynman graphs and renormalization in quantum diffusion - Erdös, László; Salmhofer, Manfred; Yau, Horng; Symposium in Honor of Wolfhart Zimmermann's 80th Birthday (World Scientific Publishing, 2008)
We review our proof that in a scaling limit, the time evolution of a quantum particle in a static random environment leads to a diffusion equation. In particular, we discuss the role of Feynman graph expansions and of renormalization.
