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 derives and interprets the spatial density distributions of the axial-vector charge density for spin-1/2 systems using sharply localized wave packets in arbitrary Lorentz frames, while also examining the static approximation and its relation to Breit-frame distributions.
This paper presents semi-analytical solutions for viscous Gubser flow with conserved charges to benchmark numerical fluid simulations, demonstrating excellent agreement between these solutions and the newly developed CCAKE Smoothed Particle Hydrodynamics code.
This paper reports the successful co-designed quantum simulation of neutrinoless double-beta decay in a 1+1D quantum chromodynamics model on IonQ's Forte trapped-ion quantum computer, where advanced compilation and error-mitigation techniques enabled the real-time observation of lepton-number violation with high precision.
This paper demonstrates that while convolutional neural networks struggle to predict jet energy loss in the presence of a QGP background, dynamic graph convolutional neural networks applied to background-subtracted particle clouds maintain high accuracy by effectively exploiting the full jet structure under realistic experimental conditions.
This study employs Monte Carlo variations of nuclear reaction rates within 1D core-collapse supernova models to demonstrate that while most reactions have minimal impact on iron-group production due to nuclear statistical equilibrium, specific "key reactions" significantly influence the synthesis of radioactive nuclei like Ti, necessitating a multi-reaction approach for accurate predictions.
This paper utilizes a 5-dimensional holographic Einstein-Maxwell model with Chern-Simons terms and a scalar field to demonstrate that explicit symmetry breaking causes anomaly-induced transport phenomena to extend beyond anomalous currents, significantly influencing non-anomalous sectors and making all conductivities sensitive to the symmetry-breaking mass parameter.
This paper utilizes Poincaré-covariant Bethe-Salpeter wave functions to calculate pion and analogue state light-front wave functions, revealing that nonperturbative dynamical effects are significant, spin-aligned components are essential for accuracy, and Gaussian approximations fail to reliably describe transverse momentum dependent distributions at higher momentum scales.
This study establishes accurate universal relations linking the fundamental, pressure, and spacetime quasinormal modes of neutron stars to their magnetic tidal deformability, demonstrating that these higher-order effects provide information about the stellar interior comparable to that of electric tidal deformability.
This study demonstrates that the phase function method can efficiently and accurately construct - scattering wavefunctions for multiple partial waves using a single-term Morse potential, achieving results consistent with both two-term potential models and resonating-group method calculations without requiring Schrödinger equation solutions.
This paper presents a systematic relativistic mean-field analysis of two-particle-two-hole meson-exchange current contributions across 17 asymmetric nuclei, proposing a novel scaling prescription that accurately models nuclear responses for neutrino event generators while benchmarking against electron-scattering data.
