Myriad systems exhibit a response that is nonlinear in amplitude, intermittent in time, and geometrically complex in space over scales that can span many orders of magnitude. Examples range from the atomic to the tectonic, including avalanches in magnetic materials, superconductors, glasses, granular media, and geological flows (earthquakes), shear thickening in dense suspensions, cracks in brittle materials, and plastic rearrangements in particle-based materials. Understanding the complex, nonlinear spatiotemporal response of these systems, and the connections between different scales is crucial for physical predictions, and for the development of reliable models for engineers. Recent theoretical and experimental progress makes this a timely forum for an interdisciplinary effort to advance this important emerging research area. One of the main goals of this program is to bring together theorists, experimentalists, and computational scientists, working on the fundamental aspects with specialists who focus on more applied aspects of far-from-equilibrium solids. The program will promote interactions between participants from statistical physics, mathematics, soft matter, condensed matter physics, and researchers at the boundary of physics and other disciplines such as materials science, solid mechanics, and geology.
