The aim of this conference is to bring together experts in quantum, classical and stochastic dynamics to exchange ideas about common methods and results in this broad field of mathematical physics. It will also be an occasion to celebrate the 80th birthday of Herbert Spohn. The conference will take place at the TUM Institute for Advanced Studies (IAS) on the Garching Research Campus and is organised and supported by the CRC TRR352 Mathematics of Many-Body Quantum Systems and Their Collective Phenomena.
