摘要: Understanding strongly interacting quantum matter and quantum gravity are both important open issues in theoretical physics, and the holographic duality between quantum field theory and gravity theory nicely brings these two topics together. In this talk, I will present how to utilize the gravity physics picture to understand quench dynamics experimentally observed in a class of random spin models realized in several different quantum systems, where the dynamics of magnetization are measured after the external polarization field is suddenly turned off. 简介：Tian-Gang Zhou received his Bachelor's degree in physics from Peking University, Beijing, China in 2020. Currently, he is a graduate student in Prof. Hui Zhai's group at Institute for Advanced Study, Tsinghua University, Beijing, China. His research interests lie in the fields of ultracold atom physics and condensed matter theory. His most recent research emphases have been on understanding the ultra-quantum matter with the methods of field theory and holographic duality.
