【研究领域和研究兴趣】

原子核物理是涉及宇宙演化,元素形成,物质基本结构的学科。本人主要从事原子核物理的理论研究,研究兴趣和领域主要包括:

1. 原子核物理的第一性原理研究。我及我的合作者将手征微扰理论得到的原子核相互作用,通过幺正关联算符方法(Unitary Correlation Operator Method, UCOM),相似重整化群方法(Similarity Renormalization Group, SRG) 等进行变换,应用到蒙特卡罗壳模型,对奇特原子核进行计算,并能够提供误差估计和精度预测。

2. 热原子核性质。在原子核协变密度泛函理论的框架下,我们采用严格保持粒子数守恒的类壳模型方法 (Shell-model-like approach, SLAP) 处理对关联, 基于系宗理论引入温度,研究原子核在有限温度下的热力学性质,例如热容、熵等,并探索对关联对原子核热力学性质的影响。我和我的合作者还致力于发展基于原子核协变密度泛函理论的,能够微观自洽研究热原子核性质的有限温类壳模型。

3. 原子核的超流性对原子核集体运动,例如反磁转动的影响。与经典的刚体转动不同,原子核的反磁转动是发生在近球形原子核的一种量子转动,它反映了原子核的内部结构,以及在该结构下发生的角动量变化。而在一定的转动频率下,原子核通常要经历从超流相到正常相的转变,研究对关联在这其中扮演的角色也是一个非常有趣的课题。

Nuclear physics is a discipline that involves the evolution of the universe, the formation of elements, and the basic structure of matter. I am mainly engaged in the theoretical research of nuclear physics, and my research interests and fields mainly include:

1. First-principles study of nuclear physics. My collaborators and I transformed the nucleus interactions obtained by the chiral perturbation theory through the Unitary Correlation Operator Method (UCOM), the Similarity Renormalization Group (SRG), etc. , Applied to the Monte Carlo shell model to calculate exotic nuclei, and can provide error estimates and precision predictions.

2. Thermal nuclei properties. Under the framework of nuclear covariant density functional theory, we adopt the Shell-model-like approach (SLAP) that strictly maintains the conservation of the number of particles to deal with pair correlations. Introducing temperature based on the theory of ensemble, we study the finite temperature of nuclei with the thermodynamic properties, such as heat capacity, entropy, etc., and explore the impact of correlation on the thermodynamic properties of atomic nuclei. My collaborators and I are also committed to developing a finite temperature shell-model-like approach based on the covariant density functional theory of atomic nuclei that can study the properties of hot atomic nuclei in a microscopic and self-consistent manner.

3. The effect of superfluidity of atomic nuclei on collective motion of atomic nuclei, such as antimagnetic rotation. Different from the classic rigid body rotation, the antimagnetic rotation of the nucleus is a kind of quantum rotation that occurs in the nearly spherical nucleus, which reflects the internal structure of the nucleus and the angular momentum change that occurs under this structure. At a certain rotational frequency, the nucleus usually undergoes a transition from a superfluid phase to a normal phase. Research on the role of correlation in this is also a very interesting topic.
