Title:
Diffusion from deterministic dynamics

Speaker:
Antti Kupiainen

Abstract:
I discuss a renormalization group method to derive diffusion from time reversible quantum or classical microscopic dynamics. I start with the problem of return to equilibrium and derivation of Brownian motion for a quantum particle interacting with a field of phonons or photons and then discuss how the method could be extended to classical coupled maps or coupled Hamiltonian systems.
