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 employs a Green's function approach within relativistic Hartree-Fock theory to demonstrate that the exact microscopical treatment of Coulomb exchange terms significantly reduces proton resonance energies and widths in isotones compared to phenomenological methods, while revealing clear shell effects in their evolution.
This paper introduces BNN-I6, a Bayesian Neural Network framework trained on ENDF/B-VIII.1 data that accurately predicts (n,p) reaction cross sections with quantified uncertainties, outperforming TENDL-2023 benchmarks while identifying theoretical cross-sections as the dominant predictive feature.
This paper demonstrates that the Superfluid -Cluster Model, by rigorously treating Nambu-Goldstone zero modes, provides a unified description of low-spin six- condensate states and high-spin C()+C() molecular resonances in Mg, identifying these states as a signature of nuclear supersolidity characterized by the coexistence of superfluidity and crystallinity.
This paper introduces a novel virtual rishon framework that enforces gauge symmetry via intermediate quantum-link representations to enable scalable simulations of lattice gauge theories in d+1 dimensions using both classical tensor networks and near-term quantum hardware, validated by benchmarking on the multi-flavor Schwinger model and 2D string tension.
This paper clarifies the origin of the geometric contribution to the superfluid density in neutron star inner crusts by deriving its dependence on the pairing gap within a multi-band framework and demonstrating that accounting for corrections to Bogoliubov quasi-particle states, rather than just Hartree-Fock single-particle states, is essential for its emergence.
This study assesses the implementation of radiation protection systems in four Ethiopian hospitals, revealing that while background and idle radiation levels are safe, poor operational practices and a lack of monitoring equipment lead to dangerously high exposure for staff during active X-ray procedures, necessitating immediate training, modern equipment, and dedicated radiation protection oversight.
Using lattice gauge theory techniques, this study analyzes the spectral properties of SU(3) gauge theory via overlap Dirac eigenvalues to reveal fractal-like clustering near the chiral crossover and estimate a thermalization time of approximately 1.44 fm/c by linking non-equilibrium chaotic momentum modes to thermal magnetic scales.
This paper utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
This paper investigates the impact of strongly-interacting dark matter, modeled by a first-principles QCD-like gauge theory, on neutron star structure and confirms that such dark matter can be accommodated within current observational constraints.
This paper challenges the interpretation of the nucleon's momentum current density as a continuous medium's pressure and shear forces, arguing instead that color interactions are long-ranged and that only the isotropic vacuum pressure term derived from the QCD trace anomaly effectively provides the confining potential for quarks.
