Tutorial 6. Non-linear Sigma Model for Disordered and Ergodic Systems

ANCILLARYEVENT · MAR-6T · ID: MAR-6T

The Non-Linear Sigma Model (NLSM) has emerged as the most universal and powerful way of describing quantum ergodic dynamics in both single-particle and many-body settings. Being constrained only by the symmetries and topology, it provides a universal description of long-time quantum evolution in ergodic and localized systems. The tutorial will highlight general principles behind NLSM, provide an accessible guidance for technical derivations and venture into applications such as localization transition, kinetics of disordered superconductors, hydrodynamics, and entanglement dynamics in monitored quantum systems.
