題目: Quantum chaos, Black holes, Periodic Table of SYK and supersymmetric SYK
時間: 2019年06月04日 10:00
地點: 中科院物理研究所M樓255會議室
報告人: 葉錦武 教授

首都師范大學,Mississippi State university

報告人簡介:

葉錦武教授,美國耶魯大學理論物理博士,首都師范大學長江學者教授,美國密西西比州立大學教授。葉教授主要研究領域是強相互作用的電子、玻色子、自旋、光子等的合作現象和量子或拓撲相變理論,他的研究還涉及超對稱性破缺、共形場論和各種量子或拓撲相的量子引力對偶。His two most recent research directions are on (1) Novel Quantum, topological Phases, phase transitions driven by interactions in various spin-orbit coupled systems. (2) quantum chaos and quantum information scramblings in cavity QED systems or in Sachdev-Ye-Kitaev models.

報告摘要:

We will first review the recent progress in SYK models and their global impacts in quantum gravity, QCD, condensed matter physics and quantum information science. Then we will outline the results achieved in our recent works in [1-5]. This colloquium is pedagogical, so should be accessible to any graduate students who are interested in working on this still rapidly expanding research direction and other related directions such as many body localization (MBL), eigenstate thermalization hypothesis (ETH), complexity, etc.
