香港大学-中国科学院大学 青年物理学者论坛

HKU-UCAS young physicist forum

 

本论坛由香港大学-中国科学院大学理论与计算物理联合研究所香港和北京分部共同承办。旨在促进青年物理学者互相的交流和讨论。不同于寻常的短平快形式的科学报告，我们主要集中于更为系统、全方位、由浅入深地讲解当前物理的各个前沿方向。报告人主要是目前活跃于科研一线的年轻学者。

 

This forum is hosted by the HKU-UCAS Joint Institute of Theoretical and Computational Physics at Hong Kong and Beijing. It aims to promote interchanges and discussions among young physicists. Different from ordinary scientific reports in the short, simple and quick form, we mainly focus on explaining and introducing various frontier directions of current physics in a more systematic, all-round way and from the shallower to the deeper. The speakers are mainly young scholars who are currently active in the front line of scientific research.

报告人简介

 

 

 

李宇，2012年本科毕业于东华大学，于2018年在中国科学院物理研究所获得博士学位。2019年-至今，于中国科学院大学卡弗里理论科学研究所从事博士后研究。研究兴趣主要关注非常规超导的微观机理，如：重费米子超导的配对对称性研究，手征超导中的Kerr效应研究，以及非费米液体超导模型中的奇异超导性质探索等。

 

Yu Li, graduated from the Donghua University in 2012, and got the PhD degree from the Institute of Physics, Chinese Academy of Sciences in 2018. From 2019 to now, he works as a postdoctoral in Kavli Institute for Theoretical Sciences, University of Chinese Academy of Sciences (KITS, UCAS). His research interests mainly focused on the unconventional superconductivity (SC), such as, pairing symmetries in heavy-fermion SCs, Kerr effect in chiral SCs, and the exploration of the novel properties in the models of non-Fermi-liquid SC.
