论文摘要
从头算核理论不仅为核多体系统的定量描述提供了微观框架，而且还提供了更深入了解新兴集体相关性的基础。从从头算预测中，通过无核配置交互方法在本次预测中确定了符号SP（3，r）$ \ supset $ u（3）动态对称性，并发现对7BE光谱提供了定性的理解。低洼状态形成Elliott SU（3）频谱，而SP（3，R）激发产生了激发的旋转带，并与基态谱带具有强连接。
Ab initio nuclear theory provides not only a microscopic framework for quantitative description of the nuclear many-body system, but also a foundation for deeper understanding of emergent collective correlations. A symplectic Sp(3,R)$\supset$U(3) dynamical symmetry is identified in ab initio predictions, from a no-core configuration interaction approach, and found to provide a qualitative understanding of the spectrum of 7Be. Low-lying states form an Elliott SU(3) spectrum, while an Sp(3,R) excitation gives rise to an excited rotational band with strong quadrupole connections to the ground state band.
