Ab initio lattice calculation of nuclear magnetic dipole moments with systematic error quantifications
Teng Wang, Serdar Elhatisari, Xu Feng +3
The paper presents the first systematic ab initio lattice effective field theory calculation of nuclear magnetic dipole moments for light nuclei and aluminum isotopes, including de…
The anomalous long lifetime of C revealed by ab initio nuclear lattice EFT
Teng Wang, Serdar Elhatisari, Xu Feng +2
The 5730-year half-life of C, the physical basis of radiocarbon dating, is anomalously long compared to typical nuclear-physics expectations. Its origin has remained a subje…
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…
Neural-network excited states of nuclei and hypernuclei
Zi-Xiao Zhang, Yi-Long Yang, Xiao-Lu Qian +4
We present the first variational Monte Carlo study of nuclear and hypernuclear excited states within the neural-network quantum states (NQS) framework. We implement both the overla…
Structure Factors for Hot Neutron Matter from Ab Initio Lattice Simulations with High-Fidelity Chiral Interactions
Yuan-Zhuo Ma, Zidu Lin, Bing-Nan Lu +6
We present the first ab initio lattice calculations of spin and density correlations in hot neutron matter using high-fidelity interactions at next-to-next-to-next-to-leading order…
Wavefunction matching for solving quantum many-body problems
Serdar Elhatisari, Lukas Bovermann, Yuanzhuo Ma +15
Ab initio calculations play an essential role in our fundamental understanding of quantum many-body systems across many subfields, from strongly correlated fermions to quantum chem…
