In spite of numerous scientific and practical applications, there is still no comprehensive theoretical description of the nuclear fission process based solely on protons, neutrons and their interactions. The most advanced simulations of fission are currently carried out within nuclear density functional theory ( DFT ). In spite of being fully quantum-mechanical and rooted in the theory of nuclear forces, DFT still depends on a dozen or so parameters characterizing the energy functional. Calibrating these parameters on experimental data results in uncertainties that must be quantified for applications. This task is very challenging because of the high computational cost of DFT calculations for fission. In this paper, we use Gaussian processes to build emulators of DFT models in order to quantify and propagate statistical uncertainties of theoretical predictions for a range of nuclea...

用Skyrme能量泛函进行核变形特性的贝叶斯分析

尽管有许多科学和实际应用，但仍没有关于仅基于质子，中子及其相互作用的核裂变过程的全面理论描述。目前在核密度泛函理论（DFT）中进行了最先进的裂变模拟。尽管完全是量子力学的，并且扎根于核力理论，但DFT仍然依赖于十几个表征能量功能的参数。在实验数据上校准这些参数会导致不确定性，必须对应用进行量化。由于用于裂变的DFT计算的高计算成本，因此该任务非常具有挑战性。在本文中，
