Description
The process of spontaneous or induced fission presents an example of large-amplitude collective motion in self-bound mesoscopic systems, exhibiting an interplay between classical and quantum effects. A wealth of experimental results has been accumulated, and a basic understanding of fission mechanism gained. In recent years, major progress has been achieved in the development of time-dependent microscopic approaches that offer a more comprehensive and predictive description of the fission process. These advances encompass the calculation of fission fragment yields [1], the characterization of energy dissipation mechanisms and total kinetic energy distributions [2,3], the study of neck formation and rupture dynamics [4], the treatment of quantum fluctuations and symmetry restoration [5], the microscopic origin of fragment angular momentum, and the analysis of quantum entanglement between the emerging fragments [6].
