Diagnosing quantum chaos in many-body systems using entanglement as a resource
Classical chaotic systems exhibit exponentially diverging trajectories due to small differences in their initial states. The analogous diagnostic in quantum many-body systems is an exponential growth of out-of-time-ordered correlation functions (OTOCs). These quantities can be computed for various m...
