On the derivation of diffusion in randomly coupled modular systems — •Pedro Alejandro Vidal Miranda and Günter Mahler — Universität Stuttgart, 1. Institut für Theoretische Physik Pfaffenwaldring 57 // IV,70550 Stuttgart ,Germany

We analyze the Schrödinger evolution of the Wigner transform of the wave function in a randomly coupled modular system in order to obtain a macroscopic equation for the dynamics of observables such as the energy. For this we average over the randomess in the system and we make use of the long time van Hove limit.
