刘海云

刘海云，2005年本科毕业于复旦大学物理系。2010年于中科院物理所超导国家重点实验室获得理学博士学位。2010-2016年先后在德国汉堡大学、马普物质结构与动态研究所从事博士后研究，以及担任束线科学家、研究学者，主要从事时间分辨角分辨光电子能谱和超快光谱学研究。2016年在北京工业大学工作，于2019年加入北京量子信息科学研究院超快光谱学团队，任副研究员。

本团队基于先进超快光谱学技术，致力于可见-红外-太赫兹频谱范围探测和研究新型量子物态的载流子动力学行为及演化规律，以及理性调控光-物质的相互作用，实现从弱耦合到强耦合的量子物态的微观机制的研究。探索超快光子束对量子物态的调控和诱变，以及超快功能性的光子学和光电子学器件。研究新型低维材料的激子-极化激元的激射及玻色-爱因斯坦凝聚体（BEC）的行为，以及室温激子极化激元BEC凝聚体在室温量子光学、一维/二维晶格以及二维量子模拟器中的应用。
