Slow dynamics in glasses, gels and foams

Slow dynamics and aging effects in disordered, out-of-equilibrium systems are a rich and fascinating topic, yet still poorly understood. Recent developments in light scattering methods, such as the multispeckle technique, combined with new theoretical approaches that underline the analogies between different glassy materials are bringing a better understanding of these phenomena.
