报告简介

　　Quantum physics has been successful for more than 100 years and is believed to be well understood. However, the concept of chaos in quantum physics is still incomplete. It may be essential for the fundamental understanding of thermalization and the microscopic nature of quantum physics. Quantum complexity is a novel quantum informational concept that is under development. Its basic idea is to quantify a "distance" between two states or operators, where "distance" may be measured by the "cost" along the path between two states (operators). Chaos and complexity are two different concepts, but they may be related to each other in certain aspects. Therefore, studying both concepts together is useful. It is also beneficial to think about the gravity dual of these concepts from a holographic perspective. For example, complexity may have physical implications for the black hole interior. In this talk, I will briefly review recent developments in quantum chaos and complexity, focusing on Krylov complexity.
