DY 30: Focus Session: New Trends in Nonequilibrium Physics – Conservation Laws and Nonreciprocal Interactions II

Wednesday, March 20, 2024, 15:00–16:30, BH-N 243

Nonequilibrium phase transitions and pattern formation are known from numerous examples of open systems, where external reservoirs and gradients prevent relaxation to thermodynamic equilibrium. In recent years, related research in biology and soft matter systems in physics and chemistry has increasingly focused on active matter, where energy is injected locally. This often involves mass conservation constraints and, in many cases, in addition non-reciprocal interactions of the involved entities, such as macromolecules or cells. Both have far reaching consequences on the universal dynamical behavior of a wide range of nonequilibrium systems and require classical concepts of nonlinear and statistical physics, such as phase transitions, to be reconsidered and developed further. For example, well-known approaches to nonequilibrium pattern formation require substantial extensions to address conserved systems. Thus, recent theoretical studies in this field have revealed many novel phenomena, such as arrested coarsening, odd elasticity, oscillatory phase separation, persistent wave dynamics, and active turbulence. Many of these aspects have by now been confirmed by experimental findings, for example, in intracellular pattern formation or collective dynamics in colloidal systems. This symposium will provide a well-balanced overview of experimental and theoretical progress in this new, exciting area.
