Macroscopic Nuclear Dynamics with Microscopic Foundations

根据所提出的研究计划，我们的目的是提取原子核反应的集体反应路径和集体惯性质量，从而分析核聚变/裂变的微观机制。在我们以前的工作中，我们成功地获得了示意图模型中的惯性质量。从2020年开始，我们对“有核子有效质量时核反应的微观集体惯性质量”的计算进行了系统的研究，这也是我们在《物理评论》C(凯文等)上发表的论文的标题。太棒了。C105,034603,2022年)，本文对我们的方法进行了扩展，对核集体惯性质量作了创新性的理解。然后，我们进行了比传统的平均场近似更高级的计算，其中包括了核配对相互作用，并应用了现代的核密度函数。这一计算需要更复杂的数值技术，最后取得了重大成就，报告了在京都举行的YITP研讨会“2022年密度泛函理论基础(DFT2022)”和在Numazu举行的2023年极端量子系统核光谱国际研讨会的初步进展。

According to the proposed research plan, our aim is to extract the collective reaction path as well as the collective inertial mass for nulcear reacions, so as to analyse the microscopic mechanism of nuclear fusion/fission. In our previous work, we succeeded to obtain the inertial masses in a schematic model. From the year 2020 we performed a systematic research on the calculations of "Microscopic collective inertial masses for nuclear reaction in the presence of nucleonic effective mass", which is also the title of the paper we published in Physical Review C (Kai Wen et.al. Phys. Rev. C 105, 034603, 2022), in this paper we extended our method and made innovative understanding on nuclear collective inertial mass. Then we performed more advanced calculations beyond the traditional meanfield approximation, where the nuclear pairing interaction is included and the modern nuclear density functionls are being applied. This calculation requires more sophisticated numerical techniques and finally significant achievements are made, preliminary progress is reported on the conferences YITP Workshop “Fundamentals in density functional theory 2022 (DFT2022)” in Kyoto and International Symposium on Nuclear Spectroscopy for Extreme Quantum systems 2023" in Numazu.
