KPZ Universality Class and Beyond - From Exact Solutions to Universal Laws

Explore the Kardar-Parisi-Zhang (KPZ) universality class through this theoretical physics seminar that examines how diverse non-equilibrium multi-component systems exhibit similar large-scale behavior despite different microscopic dynamics. Discover the broad range of phenomena unified under KPZ universality, spanning from interface growth and traffic flows to interacting random walks and polymers in random media. Learn about the analytical tools from integrable systems theory that have been developed over thirty years to describe these phenomena, including exact solutions for toy models with special mathematical structures. Examine exactly solvable models and their solutions used to study both the KPZ class and potential mechanisms for KPZ universality breaking. Gain insights into how universal statistics of fluctuations and correlations emerge independently of microscopic details, and understand the mathematical framework connecting seemingly disparate physical systems under this unified theoretical approach.
