摘要: In this talk, I will briefly introduce classical chaos, then generalize it to quantum physics. The out of time order correlation (OTOC) function which can diagnose the chaotic properties will be defined, and then I will talk about its general behaviors. The Lyapunov exponent as a direct quantity to measure the chaos has an upper bound, and I will show you why. Finally, I shall introduce the quantum chaos in a specific system.
