click here 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 106Ag 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 here relation to soft nuclear shapes.
