报告人简介：

李庆华博士博士2015年毕业于斯坦福大学，导师为祁晓亮。现在是新加坡国立大学的助理教授。他主要研究兴趣在弗罗凯和非厄米物理中新奇的非平衡物理，以及在经典和量子系统中的物理实现。

Dr. Ching Hua Lee obtained a PhD from Stanford University in 2015 under the supervision of Xiao-Liang Qi. He is current an adjunct assistant professor at the National University of Singapore, where he mainly works on novel non-equilibrium Floquet and non-Hermitian phenomena, as well as their physical realizations in various classical and quantum setups.

报告内容简介：

 传统意义上，通常假定物理系统的哈密顿量必须是厄米的。 然而，最近人们认识到，许多有趣的物理现象超出了厄密性的范式。 诸如著名的非厄米趋肤效应之类的现象可以很容易地在开放量子系统或电路等经典系统中实现。 在本次报告中，李教授将概述非厄米物理学的最新进展，特别强调在新加坡国立大学所做的工作。

Traditionally, it has usually been assumed that physical Hamiltonians must be Hermitian. However, it has recently been realized that a great variety of interesting physical phenomena lies beyond the paradigm of Hermiticity. Such phenomena such as the famed non-Hermitian skin effect can be readily realized in open quantum systems or classical systems such as electrical circuits. In this talk, Prof Lee will give an overview of recent advances in non-Hermitian physics, with special emphasis on the work done at NUS.
