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 a differentiable Bidirectional Liquid Neural Network emulator that accurately maps optical potential parameters to nucleon-nucleus scattering wave functions across a broad energy range and diverse nuclei, enabling efficient gradient-based parameter optimization and uncertainty quantification while successfully generalizing to unseen targets.
This paper calculates eleven energy-momentum tensor form factors for the deuteron using impulse approximation to map out its internal mass, momentum, stress, and force distributions, revealing how antisymmetric stress components relate to spin reorientation via torsion and how non-radial forces arise from tensor interactions and spin-orbit coupling.
This paper utilizes the Frobenius covariant to construct projection operators onto spin-S eigenspaces of total and orbital angular momenta, presenting them as both polynomials in the scalar product of these operators and expansions in polarization operators, while establishing a correspondence with Villars' angular momentum projection.
This study utilizes large-volume lattice QCD simulations at the flavor-symmetric SU(3) point to identify bound states corresponding to the , , and resonances, subsequently employing Unitary Chiral Perturbation Theory to trace their pole trajectories to the physical point.
This paper demonstrates the calculation of the deuteron binding energy on a quantum simulator using the variational quantum eigensolver with renormalization group-based effective interactions, showing that decreasing the RG parameter reduces the required qubit count while enabling noise-mitigated results that closely match experimental values.
This paper proposes three sample-efficient classical shadow protocols for lattice gauge theory that leverage gauge symmetry to achieve exponential improvements in sample complexity over symmetry-agnostic methods, offering a blueprint for simulating more general lattice gauge models.
This paper establishes a new universal relation linking the electric dipole polarizability of finite nuclei to the compactness of neutron stars, enabling the use of nuclear experimental data to constrain the neutron star radius and the slope of the symmetry energy in an equation-of-state independent manner.
This paper presents a robust, CNN-based online trigger system using compact particle histograms and a lightweight C++ inference package to effectively select quark-gluon plasma events in real-time high-rate experiments, demonstrating high accuracy and model-transfer stability across different simulation frameworks despite reconstruction effects.
This review synthesizes current knowledge of how nuclear physics governs the dynamics and multimessenger observables of binary neutron star mergers, connecting microscopic dense-matter properties to macroscopic signals like gravitational waves and kilonovae while highlighting constraints from recent observations and identifying future research directions.
This paper reviews the physical mechanisms and bottlenecks of muon-catalyzed fusion, proposes a synergistic four-step scheme to overcome alpha-sticking and achieve energy gain, and outlines a conceptual fusion-fission hybrid reactor design for breeding plutonium.
