One of the most important questions is whether such a system can return to a thermalized state under its own dynamics after a sudden quench. While thermalization is the expected behavior in many cases, there can be situations where the opposite occurs. I will start by introducing a proper definition of quantum thermalization and then explain how to theoretically determine whether an isolated quantum many-body system is in a thermalized state. Afterward, I will present the most typical example of escaping thermalization in the past decade: the phenomenon of many-body localization. This phenomenon occurs when a strong disorder is present in the system. I will briefly review the research progress in this direction and highlight the work we have done recently [1-3]. Additionally, I will discuss the problem of quantum chaos in isolated quantum systems. Specifically, we have recently investigated how to capture signals of quantum chaos in quantum circuits through out-of-time-ordered correlators (OTOC) [4].<br> [1] D. Vu, K. Huang, X. Li, and S.
