My name is Xiangrui Liu. I received a bachelor's degree in 2020 at SUSTech, now a PhD student in the Department of Physics, SUSTech. My research interest is currently focused on single crystal synthesis and electronic band structure characterisization of topological quantum materials by ARPES. Meanwhile, I am also interested in theoretical condensed matter physics, including but not limiting to the classification of topological materials, strongly correlated system and SPT. I do hope to discuss about these topics with you. In my free time , DOTA2 and basketball are my favorites.
