摘要

Abstract

Five score years ago

Mr. Po-ling Chang

founder of Nankai University in China

established its timeless motto: “

Dedication to Public Interests

Acquisition of All-Round Capability

and Aspiration for Progress with Each Passing Day

.” Today

Gui-Geng Liu

an alumnus of the 2017 Physics Po-ling Program (named after the founder of Nankai University

Mr. Po-ling Chang)

has made groundbreaking contributions to topological physics

including the realization of the first three-dimensional Chern insulator and the photonic axion insulator. He is currently an independent Principal Investigator (PI) and doctoral supervisor at the School of Engineering

Westlake University. He has published in top-tier international journals

including

Nature

Physical Review Letters

and

Science

. His research was recognized as one of the Top 10 Social Impact Events in China’s Optics in 2022. In this edition of “Light People”

I am pleased to feature Professor Gui-Geng Liu as he shares his personal journey and growth in the field.
