标题： Chiral dynamics in soft triaxial nuclei

摘要： 首次以一种微观且自洽的方式，在三维空间点阵上利用时间相关的倾斜轴回转协变密度泛函理论，研究了软三轴核的螺旋性。以令人费解的螺旋核 $^{106}$Ag 为例，在除了定义明确的密度泛函之外没有任何自由参数的情况下，成功再现了观察到的近简并带的实验能量。从总角动量的微观动力学中揭示出软三轴核中一种新的螺旋模式。这为研究螺旋性开辟了一个新的研究领域，尤其是在与软核形状相关方面。 显示英文摘要

摘要： The chirality in soft triaxial 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. Taking the puzzling chiral nucleus $^{106}$Ag as an example, the experimental energies of the observed nearly degenerate bands are well reproduced without any free parameters beyond the well-defined density functional. A novel chiral mode in soft triaxial nuclei is newly revealed from the microscopic dynamics of the total angular momentum. This opens a new research area for the study of chirality, particularly in relation to soft nuclear shapes.
