在核素图中，弱束缚原子核处于远离稳定线的区域，与稳定核相比，往往蕴含更多诸如晕结构、共振、双核子发射等奇特的现象，也更有可能涌现出一些新结构、新机制，是核物理领域研究的热点和前沿。随着新一代放射性核束装置的逐步建成，越来越多的弱束缚原子核将被合成，也给理论计算带来了更为严峻的挑战。弱束缚原子核往往是一个半开放、甚至开放的量子系统，内部的核子可以与外界环境有较强的关联，同时对计算精度也会有更高的要求。因此，为研究弱束缚原子核的奇特结构与性质，我们计划在本项目中发展能够同时包含连续谱、手征三体力与高阶多体关联的第一性原理计算方法。连续谱与高阶多体关联的引入将更加完善理论框架，而手征三体力的引入将在核力水平提高计算的精度。在此基础上，我们希望能够通过系统的理论计算与分析，揭示弱束缚原子核中奇特现象的成因与物理机制。

Weakly bound nuclei are located far away from the valley of stability on the nuclear chart. Compared with the stable nuclei, they often contain strange phenomena such as halo structure, resonance, double nucleon emission, and may emerge new structures and mechanisms, which is one of the frontiers in nuclear physics. With the construction of the new generation of radioactive ion beam facility, more and more weakly bound nuclei will be synthesized, which also brings challenges to the theoretical calculation. Weakly bound nuclei are often open quantum systems, and the internal nucleons can be strongly correlated with the external environment, which the needs high-precision calculation to describe. Based on these factors, we are going to develop an ab initio method, which includes continuum, chiral three force and high-order many-body correlation. Continuum and high-order many-body correlation will complete the model and three-body force will increase the precision. At last, we are going to systematically study the weakly bound systems and try to find out the physics behind their strange phenomena.
