Many-body quantum chaos and the butterfly effect
Quantum chaos is an ubiquitous property of many-body quantum systems. It leads to thermalization in an isolated quantum system and is also responsible for anomalous transport properties in strongly correlated materials. However, the nature of quantum chaos is a challenging problem. In this talk, I will review recent progress made in many-body quantum chaos, both theoretically and experimentally. Then I will introduce a novel approach to study many body chaos in terms of operator (observable) dynamics and apply this method to systems with various interactions. Finally, I will briefly discuss measurement protocols of the quantum butterfly effect directly in experiments.
