The deformation of many solid and granular materials is not continuous, but discrete, with intermittent slips similar to earthquakes. We discuss a simple model and experiments that reflect interesting similarities between the slip statistics of slowly compressed nano-crystals, bulk metallic glasses, granular materials, and earthquakes.The model provides many new predictions for future experiments and simulations. The studies draw on methods from the theory of phase transitions, the renormalization group, and numerical simulations.Connections to other systems with avalanches are also discussed.
