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
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
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
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
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
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
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
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
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 …
