175 – Disordered Systems
Guest: Peter Sollich Host: Markus Voelter Shownoter: Stefaan Rillaert
In this episode we talk with Peter Sollich of King’s College, London about disordered systems, statistical mechanics and complexity. In particular, we discuss the difference between quenched and annealing disorder, the relation to entropy, complexity and chaos, the formalisms used to tackle such systems as well as a whole lot of examples from physics and other sciences.
