Quantum field theory and beyond (2008): 167-182.9789812833556https://nrs.harvard.edu/URN-3:HUL.INSTREPOS:37374168We 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.en-USBrownian motionAnderson modelQuantum diffusionFeynman graphsRenormalizationJournal Article2023-02-0210.1142/9789812833556_0011
