Explore the microscopic aspects of the yielding transition in this comprehensive lecture delivered by Luca Cipelletti at the Graduate School on "Non-equilibrium Processes in Physics and Biology" held at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI). Delve into an experiment-based perspective of this complex phenomenon, building upon the foundations laid in the previous session. Over the course of 1 hour and 38 minutes, gain valuable insights into the intricate mechanisms underlying material behavior at the microscopic level during the yielding process. Enhance your understanding of non-equilibrium physics and its applications in both physics and biology through this in-depth exploration of cutting-edge research and experimental findings.
