论文摘要
首次研究了手性核的动力学，并以时间依赖性和倾斜的轴心曲柄协变密度函数理论在三维空间晶格上以显微镜和自洽的方式进行了研究。 $^{135} $ nd的两对手性双重乐队的实验能很好地再现了，而没有任何可调节的参数以外的任何可调节的参数。一种新颖的机制，即手性进动，是从体固定框架中总角动量的微观动力学揭示的，其谐波与从平面向平面旋转的过渡有关，随着自旋的增加而言。这提供了完全微观和动力学的视图，以了解核中的手性激发。
The dynamics of chiral nuclei is investigated for the first time with the time-dependent and tilted axis cranking covariant density functional theories on a three-dimensional space lattice in a microscopic and self-consistent way. The experimental energies of the two pairs of the chiral doublet bands in $^{135}$Nd are well reproduced without any adjustable parameters beyond the well-defined density functional. A novel mechanism, i.e., chiral precession, is revealed from the microscopic dynamics of the total angular momentum in the body-fixed frame, whose harmonicity is associated with a transition from the planar into aplanar rotations with the increasing spin. This provides a fully microscopic and dynamical view to understand the chiral excitations in nuclei.
