个人简介:
俞振华主要从事冷原子物理的理论研究，并探索冷原子体系在量子精密测量与传感等方面的应用。其研究成果包括：给出了强相互作用费米气体关联性质的自洽计算，弥补了以往非自洽计算破坏守恒律的缺陷；建立了描述光频原子钟碰撞频移的赝自旋理论，解释了美国国家标准与技术研究院叶军实验组的观察结果，纠正了以往普遍认为费米原子钟不会有碰撞频移的错误观念；建立了描述谐振腔中基于原子密度关联等超辐射理论，发现了费米气体费米面嵌套效应对超辐射转变的增强；揭示了三体“super Efimov”效应量子力学的基本理解；建立了p波共振气体的接触关联及其动力学理论；建立量子多体系统在外界环境中由量子混沌相到量子耗散相的相变理论，揭示了量子混沌体系与经典混沌体系的重要相似之处；发展了原子磁力计超越常规极限环轨道的非线性动力学理论。俞振华的研究获得国家基金委优青项目等诸多项目的资助。
