Macroscopic Nuclear Dynamics with Microscopic Foundations

根据提出的研究计划，我们的目标是提取核反应的集体反应路径以及集体惯性质量，从而分析核聚变/裂变的微观机制。在我们之前的工作中，我们成功地在示意模型中获得了惯性质量。从2020年开始，我们对“核子有效质量存在下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》（Kai Wen et.al. Phys. Rev. C 105, 034603, 2022）上发表的论文的标题，在这篇论文中我们扩展了我们的方法，并对核集体惯性质量有了创新的认识。然后，我们进行了超越传统平均场近似的更高级计算，其中包括核配对相互作用并应用现代核密度函数。这种计算需要更复杂的数值技术，最终取得了重大成果，在京都召开的 YITP 研讨会“密度泛函理论基础 2022 (DFT2022)”和沼津召开的国际极端量子系统核光谱研讨会 2023 上报告了初步进展。

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.
