Quantum Chaos and Eigenstate Thermalization - Lecture 3

Explore the third lecture in a series on quantum chaos and eigenstate thermalization, delivered by Mark Srednicki. Delve into the fundamental concepts of these complex topics and discover how they extend to systems without classical limits, such as Ising and Heisenberg spin systems. Learn about the role of entropy in dynamical descriptions, the challenges posed by additional symmetries, and the nature of the classical limit. Examine the relationship between these ideas and proposed alternatives like canonical typicality. This in-depth, 2-hour and 11-minute talk provides a comprehensive overview of advanced quantum mechanics concepts, suitable for researchers and graduate students in the field of theoretical physics.
