Cutoff-independent predictions from nuclear lattice effective field theory
Chen-Can Wang, Jia-Ai Shi, Bing-Nan Lu
Cutoff independence is an essential requirement for the predictive power of nuclear \textit{ab initio} calculations based on effective field theory (EFT). While it is conventionall…
Extracting Resonance Width from Lattice Quantum Monte Carlo Simulations Using Analytical Continuation Method
Zhong-Wang Niu, Shi-Sheng Zhang, Bing-Nan Lu
Nuclear lattice effective field theory (NLEFT) provides an efficient ab initio framework for computing low-lying states via imaginary-time projection. However, the extraction of un…
Charge-dependent nucleon-nucleon interaction at NLO in nuclear lattice effective field theory
Chengxin Wu, Teng Wang, Bing-Nan Lu +1
The nuclear lattice effective field theory (NLEFT) is an efficient tool for solving nuclear many-body problems, which takes high-fidelity lattice chiral interactions as input and c…
Sign-Problem-Free Nuclear Quantum Monte Carlo Simulation
Zhong-Wang Niu, Bing-Nan Lu
Quantum Monte Carlo (QMC) methods offer exact solutions for quantum many-body systems but face severe limitations in fermionic systems like atomic nuclei due to the sign problem. W…
