A novel time-ordered diagrammatic Monte Carlo method computes the Green's function for nuclei like 16O up to fifth order in a model space using on-the-fly Goldstone diagram sampling.
A combined ab initio and experimental analysis of nuclear form factors reduces uncertainties in superallowed beta-decay rates, enabling a more precise first-row CKM unitarity test.
Automated MBPT through fifth order yields converging ground-state energies for closed-shell nuclei up to 78Ni and exposes missing triples/quadruples in IMSRG(2).
FCIQMC is applied to compute ground-state energies and charge radii of ^4He, ^8Be, ^12C and ^16O at sub-percent many-body uncertainty using chiral EFT interactions.
Hartree-Fock upper bounds on lattice Hamiltonians show two-nucleon potentials do not yield accurate nuclear binding, while three-nucleon potentials saturate binding energy per nucleon through dense lattice packing rather than repulsion.
The hunter-gatherer scheme for the Magnus expansion in IMSRG(3) approximations introduces differences of up to 7 MeV in ground-state energies and 0.5 MeV in excitation energies compared to standard IMSRG(2) methods.
Symmetry-broken and equation-of-motion coupled-cluster calculations yield consistent bulk properties for Ca and Ni isotopes across medium-mass chains.
