Constraining three-nucleon forces in nuclear lattice effective field theory
Serdar Elhatisari, Ulf-G. Meißner, Zhengxue Ren +1
We study short-range three-nucleon forces (3NFs) in nuclear lattice effective field theory with a chiral two-nucleon interaction at NLO. The one-pion-exchange () and con…
Full Uncertainty Quantification of Sign-Problem-Free Quantum Monte Carlo Methods and Nuclear Lattice Effective Field Theory Benchmarks
Zhong-Wang Niu, Bing-Nan Lu, Shuang Zhang +4
Sign-problem-free quantum Monte Carlo (QMC) methods provide one of the few polynomial-scaling routes to controlled, nonperturbative benchmarks of medium-mass and heavy nuclei. We p…
Nuclear charge radii of aluminium isotopes at the proton drip line
Alex Brinson, Brooke Rickey, Pierre Arthuis +35
Understanding the evolution of nuclear size away from stability remains a central challenge in nuclear physics. In neutron-deficient systems, charge radii can be highly sensitive t…
Multi-neutron correlations in light nuclei via ab-initio lattice simulations
Shuang Zhang, Serdar Elhatisari, Ulf-G. Meißner
The quest to understand multi-neutron systems has a long history, and recent experimental efforts aim to probe candidate four-neutron configurations in neutron-rich light nuclei su…
Lattice simulation of nucleon distribution and shell closure in the proton-rich nucleus Si
Shuang Zhang, Serdar Elhatisari, Ulf-G. Meißner +1
The proton-rich nucleus Si is studied using Nuclear Lattice Effective Field Theory with high-fidelity chiral forces. Our results indicate that Si is more tightly boun…
