Mathematics Webinar | Non-Equilibrium Dynamics and Weak Chaos in Hamiltonian and Driven Systems, 7 July 2025
Understanding the long-term behavior of complex systems far from equilibrium remains one of the central challenges in nonlinear science. This workshop brings together recent advances in the study of non-equilibrium dynamics and weak chaos in both Hamiltonian many-body systems and externally driven (non-autonomous) models. Topics will include ergodicity breaking, metastable and quasi-stationary states, energy localization, and anomalous transport, as well as the use of diagnostic tools such as Lyapunov exponents and SALI to characterize dynamical behavior. Particular emphasis will be placed on systems with long-range interactions and mean-field models that exhibit integrable-like features in the thermodynamic limit, and on periodically forced systems where scattering, resonance, and sensitivity to external parameters play key roles in trajectory evolution. By exploring the interplay between structure, stability, and weak forms of chaos, this workshop aims to deepen our understanding of how order and unpredictability coexist in nonlinear dynamical systems. We invite researchers working across mathematical physics, dynamical systems theory, and computational modelling to attend, with the goal of fostering interdisciplinary dialogue and identifying new directions for exploration.
