    An approach called wavefunction matching transforms particle interactions so that their wavefunctions match those of easily computable interactions, to allow for calculations of quantum many-body systems that would otherwise be difficult or impossible.

    The physics of dense matter extracted from neutron star collision data is demonstrated to be consistent with information obtained from heavy-ion collisions, and analyses incorporating both data sources as well as information from nuclear theory provide new constraints for neutron star matter.

    γ-ray spectroscopy experiments on the origin of spin in the products of nuclear fission of spin-zero nuclei suggest that the fission fragments acquire their spin after scission, rather than before.

    A mechanistic explanation for the origin of the neutron dripline shows that nuclei accommodate the addition of neutrons by becoming increasingly ellipsoidal, up to a maximum number of neutrons, reconciling theory and experiments.

    Observations of the decay of 73Sr, when compared to its mirror nucleus 73Br, indicate that the spin assignment of their ground states differ, demonstrating mirror-symmetry violation.

    High-energy electron scattering that can isolate pairs of nucleons in high-momentum configurations reveals a transition to spin-independent scalar forces at small separation distances, supporting the use of point-like nucleon models to describe dense nuclear systems.

    Simultaneous high-precision measurements of the EMC effect and short-range correlated abundances for several nuclei reveal a universal modification of the structure of nucleons in short-range correlated neutron–proton pairs.

    Electron-scattering experiments reveal that the fraction of high-momentum protons in medium-to-heavy nuclei increases considerably with neutron excess, whereas that of high-momentum neutrons decreases slightly, in contrast to shell-model predictions.

    Two singly charmed baryons can fuse into the recently discovered doubly charmed baryon and a neutron through an exothermic reaction analogous to the nuclear fusion between deuterium and tritium.

    An ab initio calculation of alpha–alpha scattering is described for which the number of computational operations scales approximately quadratically with particle number and which uses lattice Monte Carlo simulations and lattice effective field theory, combined with the adiabatic projection method to reduce the eight-body system to a two-cluster system.

    The exotic double-gamma nuclear decay has been observed in cases where the usual single-gamma decay is forbidden, but now a double-gamma decay of excited 137Ba is reported that is in competition with a single-gamma decay.

    The masses of the exotic calcium isotopes 53Ca and 54Ca measured by a multi-reflection time-of-flight method confirm predictions of calculations including nuclear three-body interactions.

    Nuclear density functional theory is used to calculate the uncertainty in the positions of the neutron and proton ‘drip lines’, and to estimate that there are around 7,000 bound nuclides containing between 2 and 120 protons.
