人工光子微结构中非厄米量子现象的实验研究

Experimental study of non-Hermitian quantum phenomena in artificial photonic microstructure

真实世界中的开放体系大都是非厄米体系,研究非厄米体系在基础研究和前沿应用等方面都具有重要的价值.人工光子微结构为探索非厄米量子现象提供了研究平台.介绍了宇称-时间对称系统和奇异点的基本理论,概述了基于光子晶体、超材料、表面等离子激元等人工光子微结构系统中非厄米量子效应实验研究的最新进展,并展示了其相关的应用前景.

Since most of the open systems in real world are non-Hermitian systems,it is of great value to study non-Hermitian systems in many aspects the as fundamental research and frontier applications.The artificial photonic microstructure can provide a research platform for exploring such non-Hermitian phenomena.In this article,the basic theory of parity-time symmetric systems and singularities was introduced.The recent progresses in the experimental study of non-Hermitian quantum effects in artificial photonic microstructures based on photonic crystals,metamaterials and surface plasmon polaritons were demonstrated,as well as related application prospect of artificial photonic microstructures.
