Introduction

A large variety of physical systems respond to smooth continuous driving forces in an intermittent and stochastic way resulting in avalanche processes. Examples cover the range from the atomic to the tectonic scales, including avalanches in magnetic materials, superconductors, deformation of glasses and metals, cascades of irreversible rearrangements in soft matter systems, dynamics of imbibition fronts and crack growth; fracture of heterogeneous materials, mechanical response of granular and porous media, geological flows, such as snow avalanches, land slides, and earthquakes, and the bursting activity of neural networks. In many cases the avalanche processes show a certain degree of criticality, with absence of characteristic scales, and power-law decays of the temporal and spatial correlations. The aim of this interdisciplinary workshop is to provide an overview of recent developments of these seemingly very different processes and to find the general common trends, approaches, and tools which can help to advance this important emerging research field.

Contributions are expected on recent experimental results as well as theoretical studies including modeling and mathematical tools for the analysis of avalanche processes.

The workshop is the continuation of a series of four previous meetings: “Crackling noise and intermittency in Condensed Matter​” held in Göttingen (Germany) in May 2013,  “Avalanches in Functional Materials and Geophsyics” held in Cambridge (UK) in December 2014, „Workshop on Avalanche Processes in Condensed Matter Physics and Beyond” held in Barcelona (Spain) in January 2017, and „Avalanche dynamics and precursors of catastrophic events” held in les Houches (France) in February 2019.
