Nuclear fission is a fascinating field of research that involves large-amplitude collective dynamics of a microscopic many-body system. Specifically, the process of spontaneous-fission decay can only be explained within the quantum tunneling phenomenon. The present review discusses recent advancements in the theoretical understanding of spontaneous fission. These concern precise prediction of the spontaneous fission observables like fission lifetime and distribution of fragment yields. The theoretical developments presented here are based on a coherent coupling between the adiabatic collective dynamics and the static inputs obtained from the nuclear energy density functional formalism.

核裂变是一个引人入胜的研究领域，涉及微观多体系统的大振幅集体动力学。具体来说，自发裂变的衰变过程只能在量子隧穿现象中进行解释。本文对自发裂变的理论认识进行了讨论。这些涉及对自发裂变观测值的精确预测，例如裂变寿命和碎片产量的分布。这里提出的理论发展是基于绝热集体动力学与从核能密度泛函形式获得的静态输入之间的相干耦合。
