个人研究情况简介

背景介绍宇宙里面的剧烈天文事件,如宇宙大爆炸之后的强子化过程,超新星爆发、中子星形成及演化等都与高密核物质性质有关。美国、欧洲最近的核物理长期规划都明确提出将致密核物质性质及强子-夸克相变研究作为主要研究内容之一。我国的强流重离子加速装置已动工建设。本人主要以高密核物质性质探测相关理论为研究对象,基于重离子碰撞输运模型,结合实验,给出高密核物质状态方程及高重子核物质相变边界信息,帮助人们理解宇宙相关演化过程,增加人们对非微扰QCD强相互作用的认识。

取得成就:主要致力于研究中低能区重离子碰撞前沿热点中的冷问题。从事相对独立的科研十多年来,在同位旋相关输运理论模型的发展,高密对称能的探测及约束,重离子碰撞中的核子-核子短程关联效应及粒子产生,致密核物质状态方程及核物质相变等方面做了一系列具有创新性的系统性研究工作,如约束了原子核里核子运动的有效动量;提出非对称核物质核子运动的动量隙概念;发展建立了同位旋与短程关联相关的输运理论模型;提出“同位旋阻塞”概念;指出输运模型框架严重影响高密对称能实验数据的解读;提出高密对称能的定性探测方法;提出并研究了对称能探测密度区间问题;指出高密对称能实验室探测存在盲点;提出利用挤压核子发射、光子产生及具有隐奇异夸克的介子作为探测高密对称能的新探针;发现超强磁场条件下中能重离子核反应可以产生类中子星物质;提出在低能核反应实验中可以通过探测饱和点对称能的曲率约束高密核物质对称能;提出研究由核子物质到夸克物质相变密度的新方法;提出双奇异粒子较单奇异粒子更适合探测高密核物质性质;给出已知最致密强子物质状态方程探测新方法以及发生强子-夸克相变的最低重子数密度;提出通过三核碰撞新模式来研究超重元素合成及高密核物质性质;另外还提出探测研究第五种力及原子核空心结构的新方法等等。

至今在国际期刊发表研究性论文50多篇,其中20篇发表在顶级物理研究性期刊 Phys. Rev. Lett., Phys. Lett. B 及 Phys. Rev. C快报上;是国内本领域相对独立发表快讯、快报类创新性文章最多的人之一;美国物理评论Physical Review C、中国物理Chinese Physics C 等期刊评审人;国家自然科学基金、教育部硕博学位论文等评审人;主持、参与多项国家自然科学基金面上、重点及中科院先导项目。
