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.

核物理学的主要挑战之一是了解和预测稳定和外来核的特性，三核（3N）力至关重要并具有当前的边界。该项目将独特地将强大的多体方法应用于强烈相互作用的核系统，在中等质量和较重的中子核中，系统地实现3N力，并使用相似性重新归一化组（SRG）方法在动量空间中，以及中等空间中的中等水平方法，用于一致的价值计算。手性有效野外理论（EFT）为核力量提供了系统的基础，包括一致的多体力和理论不确定性。随着理论和计算的进步，我处于关键位置，将实验室中的观察结果与核定特性的强大相互作用联系起来。
