| Open AccessElucidating the nature of the proton radioactivity and branching ratio on the first proton emitter discovered 53mCo
Since the discovery of proton radioactivity in 53mCo, there has been no direct measurement of its branching ratio. Here the authors report the first measurement of the weak proton decay in 53mCo by combining results from advanced detection systems.

| Open AccessExpanding the limits of nuclear stability at finite temperature
It is interesting and important to understand how the properties of nuclei and their stability change with temperature. Here the authors report their theoretical study of hot nuclei and the drip lines that limit the nuclear existence at finite temperature.

| Open AccessQED radiative corrections for accelerator neutrinos
Precisely calculating differences between muon- and electron-neutrino interactions is difficult, but is vital for correctly interpreting neutrino oscillation experiments. Here, the authors determine the effect of electromagnetic quantum corrections in the predicted ratio of ve and vμ cross sections.

| Open Accessα-Clustering in atomic nuclei from first principles with statistical learning and the Hoyle state character
Alpha particles are considered the building blocks for some nuclei in alpha-clustering. Here the authors discuss quantum many-body simulations with nucleon-nucleon interaction to characterize the Hoyle state, the first excited 0+ state of the 12C nucleus, and find complexity in its alpha-clustering.

| Open AccessSU(2) hadrons on a quantum computer via a variational approach
Quantum simulations of lattice gauge theories are in principle scalable, but their extension to dynamically coupled matter has proven difficult. In this work, the authors use a variational quantum eigensolver to simulate a non-Abelian LGT including the effects of both gauge fields and dynamical fermions.

| Open Access4D-imaging of drip-line radioactivity by detecting proton emission from 54mNi pictured with ACTAR TPC
Proton radioactivity is useful for studying nuclear structure. Here the authors report two proton emission branches from the 10+ state isomer of 54mNi by using a time projection chamber.

| Open AccessEvidence of a sudden increase in the nuclear size of proton-rich silver-96
Laser spectroscopic measurements of isotopes near the doubly-magic 100-Sn are challenging due to difficulties in their production. Here the authors measure the ground state charge radius of the proton-rich 96-Ag isotope and find a discontinuity in the nuclear size when crossing the neutron number N equal to 50.

| Open AccessMeasurement of the neutron charge radius and the role of its constituents
The charge radius of nucleons provides information about their structure. Here the authors present a method, based values of neutron electric form factors, to determine the charge radius of the neutron and provide information on improving the uncertainty of neutron charge radius measurements

| Open AccessElectromagnetic character of the competitive γγ/γ-decay from 137mBa
Second order effects can play an important role in highlighting nuclear structure properties. Here, the authors show how the second-order nuclear transitions in the form of double-gamma decay in 137Ba help understanding atomic nuclei.

| Open AccessAb initio predictions for polarized deuterium-tritium thermonuclear fusion
Thermonuclear fusion of nuclei of deuterium and tritium may provide the energy for the future and spin polarization is a potential mechanism for enhancing the nuclear reaction. Here the authors predict the enhanced DT fusion rate using chiral effective field theory and ab initio calculations.

| Open AccessEvidence for prevalent Z = 6 magic number in neutron-rich carbon isotopes
Magic numbers are associated with the stability of atomic nuclei. Here, the authors analyse the proton radii, binding energies and electric quadrupole transition rates of neutron-rich carbon isotopes at proton number six and use nuclear structure models to support the magic number Z = 6.

| Open AccessAn equation-of-state-meter of quantum chromodynamics transition from deep learning
The large data generated in heavy-ion collision experiments require careful analysis to understand the physics. Here the authors use the deep-learning method to sort equation of states in QCD transition and analyze the simulated data sets mimicking the heavy-ion collision experiments.
