Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper presents numerical simulations of Model F using a Metropolis algorithm to investigate the critical dynamics of the superfluid phase transition, successfully reproducing the expected dynamical exponent and observing a propagating second sound mode whose diffusivity follows the predicted scaling relation with the correlation length.
This paper develops a Bayesian inference framework to disentangle genuine collective flow from transverse momentum conservation (TMC) backgrounds in small collision systems, revealing that while +Pb data aligns with standard flow measurements, + collisions require this new method to accurately extract flow magnitudes that are otherwise underestimated due to competing TMC effects.
This paper proposes lepton number violation (LNV) reactions on nuclei at accelerators as a promising new approach to quantitatively study lepton number violation, such as in double beta decay, by investigating heavy ion double single charge exchange and direct Majorana double charge exchange reactions alongside isotensor two-body transition densities and pion potentials.
This paper employs systematic cranked shell model calculations to successfully reproduce experimental rotational properties and elucidate the shape evolution, including -softness and shape coexistence, of odd-mass neutron-rich bromine isotopes Br.
This paper proposes and analyzes lepton double charge exchange reactions (X) at multi-GeV accelerator facilities as a feasible and powerful probe for lepton number violation and physics beyond the Standard Model, predicting sizable cross sections driven by left-right mixing and heavy neutral leptons that are free from the constraints of traditional decay or capture experiments.
This study presents the first survey of octupole deformation and other ground-state properties in heavy actinide nuclei using Fayans energy density functionals, demonstrating their accuracy against experimental data and showing trends consistent with previous Skyrme-based models.
Motivated by color coherence and decoherence effects, this paper proposes a theoretical framework combining vacuum-like evolution and medium-induced radiation to successfully describe the inclusive jet modification factor and its substructure dependence in 0–10% PbPb collisions at as measured by ATLAS.
Using first-principles lattice simulations with an exact center symmetry induced by a specific imaginary isospin chemical potential, this study demonstrates that QCD with three degenerate dynamical quarks undergoes a first-order deconfinement phase transition and maps its behavior in the mass-isospin chemical potential plane.
This study investigates s-wave kaon condensation in neutron-star matter using an updated Chiral Mean Field model with dynamically generated meson masses, finding that the onset of condensation at 2–8 times nuclear saturation density leads to variable softening of the equation of state while remaining consistent with observed 2-solar-mass neutron stars and producing distinct thermal cooling signatures.
This study applies the Random Forest algorithm to successfully reproduce observed decay modes and half-lives in superheavy nuclei, predicting that alpha decay will dominate for elements Z=119–122 while identifying a potential long-lived spontaneous fission island southwest of Fl.
