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.
