核第一性原理(或称从头算)研究因其可靠的预测和指导实验的能力而成为理论核物理研究的前沿。它通过手征有效场论将低能核物理与基本理论(量子色动力学QCD)联系起来。在过去的几十年里，得益于量子多体方法和计算机硬件的发展，从头算方法取得了巨大的成功。利用创新的量子多体方法和适合于低能核子-核子散射数据的手征势，从头算计算已经从轻质量核推到了重质量核，从束缚良好的稳定核推到了弱束缚核或非束缚核。在过去的几年里，我们一直致力于探索从头计算中的两个方面：手征三体力和连续体效应。手征三体力已被证明对有限核和核物质的性质都有广泛的影响。连续谱效应是计算弱结合核或非结合核的关键因素。本文回顾了手征三体力和考虑连续介质耦合的从头算Gamow壳模型的一系列研究成果。
Nuclear first-principles (or called ab initio ) studies are the frontier of theoretical nuclear physics research for their reliable predictions and the ability to guide experiments. It bridges low-energy nuclear physics and the fundamental theory (quantum chromodynamics QCD) through the Chiral effective field theory. In past decades, ab initio methods have gained great success, benefiting from developments of quantum many-body methods and computer hardware. Using the innovative quantum many-body methods and the chiral potential that is fitted to low-energy nucleon-nucleon scattering data, ab initio calculations have been pushed from the light mass nuclei to heavy mass nuclei, from well-bound stable nuclei to weakly bound or unbound nuclei. During pasting years, we have been concentrating on exploring two aspects in ab initio calculations: chiral three-body forces and continuum effects. Chiral three-body forces have been shown to have broad influences on both the properties of finite nuclei and nuclear matter. Continuum effects are the key ingredient in the calculations of weakly bound or unbound nuclei. This paper reviews the series of achievements that we gained in the development of chiral three-body forces and ab initio Gamow shell model which takes the continuum coupling into account.
