摘要：
Applying the effective field theory (EFT) in nuclear ab initio calculations has become 
increasingly popular in recent years. However, a direct implementation of the EFT paradigm 
yields non-unique results that sensitively depend on the momentum cutoff Λ. This is quite 
unsatisfactory as Λ is an artificial unobservable and must be excluded from any reliable 
prediction. In this talk I will discuss this issue in detail and show how to build an 
inherently renormalization-group-invariant (Λ-independent) EFT. Our method is a non-
relativistic counterpart of the renowned Wilsonian renormalization group theory and can 
be applied to most general many-body EFTs. I will also present numerical demonstrations 
with realistic chiral EFT, then discuss the possibility of making truly model-independent
predictions in nuclear ab initio calculations.

报告人简介：
吕炳楠，中国工程物理研究院研究生院研究员. Dr. Bing-Nan Lu is a researcher in the Graduate School 
of China Academy of Engineering Physics since 2020/09. Before that he was a post-doc 
researcher in Jülich Research Center (Germany) and Michigan State University (US). He 
obtained his PhD in 2012/07 at the Institute of Theoretical Physics, Chinese Academy of 
Sciences. His research interest is ab initio methods in nuclear physics, more generally, 
designing and implementing advanced algorithms for numerically solving the quantum many-body
problems.
