One of the central challenges in nuclear physics is to understand and predict the properties of stable and exotic nuclei, for which three-nucleon (3N) forces are crucial and present a current frontier. This project will uniquely apply powerful many-body methods to strongly interacting nuclear systems, systematically implementing 3N forces in many-body calculations of medium-mass and heavier neutron-rich nuclei using similarity renormalization group (SRG) methods in momentum space and in-medium for consistent calculations of valence-shell interactions and electroweak operators. Chiral effective field theory (EFT) provides a systematic basis for nuclear forces including consistent many-body forces and theoretical uncertainties. With theoretical and computational advances, I am in a key position to connect the observations made in the laboratory to the underlying strong interactions governing the properties of nuclei.

核物理学的核心挑战之一是理解和预测稳定和奇异核的性质，其中三核子（3N）力是至关重要的，并提出了当前的前沿。该项目将独特地将强大的多体方法应用于强相互作用的核系统，在中等质量和较重的富中子核的多体计算中系统地实施3N力，在动量空间和介质中使用相似重整化群（SRG）方法，用于一致计算价壳层相互作用和电弱算子。手征有效场论（EFT）为核力提供了一个系统的基础，包括一致的多体力和理论的不确定性。随着理论和计算的进步，我处于一个关键的位置，将实验室中的观察结果与控制原子核性质的潜在强相互作用联系起来。
