Description

Venue

Nordita, Stockholm, Sweden

Scope

Numerous systems including deformation and fracture of materials, dynamics of domain walls in ferromagnets, and earthquakes respond to slow and smooth external driving by exhibiting intermittent and bursty dynamics, or ”crackling noise”, consisting of a sequence of events with a broad size distribution. A major challenge we aim to address within this program is that in many cases, the relevant empirical and experimental phenomena remain unexplained by theory. To this end, we plan to bring together experts of various fields where crackling noise is observed, including contributions from theory, numerical simulations and experiment, to present an overview of the current developments, and to discuss open problems of the field.
