Chaos and Relaxation in a Dissipative Sachdev-Ye-Kitaev Model

Explore the intricate relationship between chaos and relaxation in the Sachdev-Ye-Kitaev (SYK) model through this comprehensive lecture. Delve into the study of how chaos affects the relaxation process to equilibrium when the SYK model interacts with its environment. Discover the fascinating phenomenon of anomalous relaxation, even in scenarios where environmental coupling approaches zero. Gain insights into the technical aspects of solving Schwinger-Dyson equations for Lindblad evolution using both Euclidean time and real-time Keldysh formalism. Examine the interpretation of results through the lens of non-Hermitian vectorized Lindblad operator spectra. Enhance your understanding of this solvable many-body theory known for its maximal chaotic behavior in low-temperature conditions.
