An ICTP Meeting

Seventy years after the Fermi-Pasta-Ulam-Tsingou investigations, we revisit its legacy in classical and quantum systems, exploring slow relaxation, ergodicity breaking, and emergent phenomena shaping modern nonlinear and many-body physics.

Seventy years after the pioneering numerical experiment of Fermi, Pasta, Ulam, and Tsingou, the study of slow dynamics in many-body systems continues to inspire fundamental research across physics. The unexpected persistence of non-ergodic behavior in nonlinear oscillator chains opened a path to modern investigations of thermalization, integrability, and chaos. Today, these themes extend well beyond the classical realm, shaping our understanding of quantum quenches, many-body localization, prethermalization, and emergent hydrodynamics. This conference brings together mathematicians and physicists to assess the legacy of the FPUT problem, highlight recent advances, and explore future directions in both classical and quantum dynamics.

Topics:

• Slow dynamics in many body systems
• Thermalization, ergodicity, and its breaking in many-body system
