汪忠

汪忠，男，清华大学高等研究院教授. 本科毕业于中国科学技术大学近代物理系，2011年获博士学位。2011年起在清华大学高等研究院工作。2021年获国家杰出青年科学基金. 主要研究领域为凝聚态物理，同时关注若干交叉方向。目前主要研究方向为拓扑物态与拓扑现象，关联量子物态，以及非厄米物理.

研究工作包括: 提出了非布洛赫能带理论(non-Bloch band theory), 并应用于非厄米拓扑体系, 建立了非厄米体边对应关系。提出了广义布里渊区(generalized Brillouin zone)、非厄米趋肤效应(non-Hermitian skin effect)等概念。其理论预言被国内外多项实验证实。提出了基于零频格林函数的拓扑不变量，为研究关联体系中的拓扑物态提供了一个理论工具。
