A Guided Tour of ab initio Nuclear Many-Body Theory

H Hergert - Frontiers in Physics, 2020 - frontiersin.org
Over the last decade, new developments in Similarity Renormalization Group techniques
and nuclear many-body methods have dramatically increased the capabilities of ab initio …

Evolution of shell structure in exotic nuclei

T Otsuka, A Gade, O Sorlin, T Suzuki, Y Utsuno - Reviews of modern physics, 2020 - APS
The atomic nucleus is a quantum many-body system whose constituent nucleons (protons
and neutrons) are subject to complex nucleon-nucleon interactions that include spin-and …

Discrepancy between experimental and theoretical β-decay rates resolved from first principles

P Gysbers, G Hagen, JD Holt, GR Jansen, TD Morris… - Nature Physics, 2019 - nature.com
The dominant decay mode of atomic nuclei is beta decay (β-decay), a process that changes
a neutron into a proton (and vice versa). This decay offers a window to physics beyond the …

Accurate bulk properties of nuclei from to from potentials with isobars

WG Jiang, A Ekström, C Forssén, G Hagen, GR Jansen… - Physical Review C, 2020 - APS
We optimize Δ-full nuclear interactions from chiral effective field theory. The low-energy
constants of the contact potentials are constrained by two-body scattering phase shifts, and …

Recent advances in chiral EFT based nuclear forces and their applications

R Machleidt, F Sammarruca - Progress in Particle and Nuclear Physics, 2024 - Elsevier
During the past two decades, chiral effective field theory has evolved into a powerful tool to
derive nuclear forces from first principles. Nearly all two-nucleon interactions have been …

High-quality two-nucleon potentials up to fifth order of the chiral expansion

DR Entem, R Machleidt, Y Nosyk - Physical Review C, 2017 - APS
We present NN potentials through five orders of chiral effective field theory ranging from
leading order (LO) to next-to-next-to-next-to-next-to-leading order (N 4 LO). The construction …

Chiral interactions up to next-to-next-to-next-to-leading order and nuclear saturation

C Drischler, K Hebeler, A Schwenk - Physical Review Letters, 2019 - APS
We present an efficient Monte Carlo framework for perturbative calculations of infinite
nuclear matter based on chiral two-, three-, and four-nucleon interactions. The method …

78Ni revealed as a doubly magic stronghold against nuclear deformation

R Taniuchi, C Santamaria, P Doornenbal, A Obertelli… - Nature, 2019 - nature.com
Nuclear magic numbers correspond to fully occupied energy shells of protons or neutrons
inside atomic nuclei. Doubly magic nuclei, with magic numbers for both protons and …

Ab Initio Limits of Atomic Nuclei

SR Stroberg, JD Holt, A Schwenk, J Simonis - Physical Review Letters, 2021 - APS
We predict the limits of existence of atomic nuclei, the proton and neutron drip lines, from the
light through medium-mass regions. Starting from a chiral two-and three-nucleon interaction …

Multiscale physics of atomic nuclei from first principles

ZH Sun, A Ekström, C Forssén, G Hagen, GR Jansen… - Physical Review X, 2025 - APS
Atomic nuclei exhibit multiple energy scales ranging from hundreds of MeV in binding
energies to fractions of an MeV for low-lying collective excitations. As the limits of nuclear …
