Integrability and Nonequilibrium Phenomena in Spacetime-Modulated Systems

Many physical systems of current interest operate far from equilibrium, where external driving, time-dependent interactions, and spatial modulation lead to rich and sometimes unexpected behavior. Examples range from periodically driven (Floquet) quantum systems to classical and quantum field theories with time-dependent couplings. Understanding such systems is a major challenge across condensed matter physics, statistical physics, high-energy theory and cosmology.

 

This workshop aims to bring together researchers studying nonequilibrium dynamics from complementary perspectives, with a particular focus on systems that retain special mathematical structures known as integrability. These structures allow exact or highly controlled descriptions of dynamics, even far from equilibrium, and have recently been identified in a growing number of time- and spacetime-modulated models both in high energy and condensed matter physics.

 

Topics will include driven and integrable systems with spatially modulated couplings, Floquet systems, relaxation and transport in nonequilibrium settings, and the use of integrability-based methods to analyze dynamical phenomena. Special emphasis will be placed on connecting recent developments on time-dependent integrable quantum mechanical models relevant to condensed matter physics with time-dependent integrable sigma models studied in high-energy physics.

 

By creating a common forum for researchers from different communities, the workshop seeks to encourage dialogue, clarify shared concepts, and highlight unifying principles underlying nonequilibrium behavior in spacetime-modulated systems. The program will emphasize interaction and discussion, with the goal of inspiring new collaborations and future research directions.
