核能密度泛函（EDF）在再现核素表中原子核的性质方面有着悠久的历史。它们定量地捕获束缚核的紧急特征，例如核饱和和配对，但积极寻求更高的准确性和改进的不确定性量化。现象学EDF的实现暗示了有效场论（EFT）的公式，并暗示了潜在的功率计数。在试图将核EDF方法转变为适当的EFT时，可能有多种途径。我对目前的情况进行了评论，并推测如何使用有效的行动方案。
Nuclear energy density functionals (EDFs) have a long history of success in reproducing properties of nuclei across the table of the nuclides. They capture quantitatively the emergent features of bound nuclei, such as nuclear saturation and pairing, yet greater accuracy and improved uncertainty quantification are actively sought. Implementations of phenomenological EDFs are suggestive of effective field-theory (EFT) formulations and there are hints of an underlying power counting. Multiple paths are possible in trying to turn the nuclear EDF method into a proper EFT. I comment on the current situation and speculate on how to proceed using an effective action formulation.
