Rejuvenation and Memory: Amazing Effects in Spin Glass Dynamics

Explore the fascinating world of spin glass dynamics in this 49-minute lecture by Federico Ricci-Tersenghi. Delve into the intriguing phenomena of rejuvenation and memory effects in disordered magnets, which have long puzzled researchers due to their complex out-of-equilibrium dynamics. Discover how cutting-edge large-scale numerical simulations, powered by the Janus 2 dedicated computer, have finally succeeded in reproducing these elusive effects. Gain insights into the microscopic explanations behind these phenomena, involving multiple growing length scales, and understand why such measurements are currently only achievable through numerical simulations. Uncover the groundbreaking research that sheds light on the behavior of spin glasses at low temperatures and their inability to reach equilibrium even on experimental time scales.
