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 microscopic Skyrme Hartree-Fock-based folding potential model to simultaneously describe low-energy elastic scattering and calculate the astrophysical factor for the He()Be reaction, yielding a recommended zero-energy value of keV b that agrees well with experimental data.
This review paper outlines the physics prospects of proposed Super Tau-Charm Factories, highlighting their unique capabilities in high-luminosity electron-positron collisions to advance precision tests of the Standard Model, explore CP violation, study tau and charm properties, and investigate nonperturbative QCD phenomena.
This paper proposes a quantum algorithm that utilizes time-dependent wave-packet evolution on a finite lattice in Cartesian coordinates to efficiently compute scattering matrices and reaction cross-sections for nuclear and chemical processes, offering a scalable approach for future fault-tolerant quantum hardware.
This study demonstrates that while weak-interaction-driven bulk viscosity renders dissipative tidal effects undetectable, the conservative dynamical tidal response of neutron stars offers a promising gravitational-wave probe for constraining higher-order coefficients of the nuclear symmetry energy.
This paper introduces a global, physics-constrained machine-learning emulator that quantitatively links nuclear electromagnetic moments to specific components of chiral nuclear forces, revealing their unique sensitivity to spin and isospin sectors and enabling uncertainty-quantified predictions for observables beyond current experimental reach.
This paper investigates the QCD phase diagram using the Nambu–Jona-Lasinio model with density-dependent screening effects, revealing that these corrections shift the position of the Critical End Point and alter the nature of the chiral transition, thereby offering theoretical insights for heavy-ion experiments and compact star physics.
This paper proposes that large lepton flavor asymmetries in the early Universe could trigger a pion condensation phase, producing a distinctive imprint on the low-frequency gravitational wave spectrum that offers a novel way to constrain early Universe lepton asymmetries and potentially explain signals observed by Pulsar Timing Arrays.
This paper reformulates stellar structure equations as a dynamical system to demonstrate that the maximum mass of stellar sequences corresponds to a fixed point in the relativistic regime, a framework that explains equation-of-state-insensitive relations and suggests that the pulsar J0740+6620 likely lies near this maximum only if a strong first-order phase transition occurs just above its central density.
This paper investigates the late-time asymptotic behavior and attractor structure of spin density in minimal causal spin hydrodynamics under Gubser flow, demonstrating that in specific regimes, spin density decays as a hydrodynamic mode governed by late-time scaling laws similar to conventional thermodynamic variables.
This study investigates the interaction of accelerator neutrinos up to 55 MeV with I nuclei at the SNS, calculating cross sections that reveal the dominant contribution of the Gamow-Teller resonance GTR-1 (60–80%) alongside significant effects from higher resonances GTR-2 and AR-2, with theoretical results showing agreement with experimental data below the neutron separation threshold.
