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 introduces a new thermodynamic state function to compute high-order temperature fluctuations in hot QCD matter, revealing that these fluctuations are significantly suppressed and exhibit negative skewness during the transition from a hadron resonance gas to a quark-gluon plasma due to the increased heat capacity of the latter.
This paper presents the first non-linear numerical simulation of spherically symmetric neutron stars using the causal and stable BDNK viscous hydrodynamics framework under the Cowling approximation, demonstrating stable evolutions and analyzing quasi-normal mode frequencies as a foundational step toward fully consistent astrophysical models.
This paper introduces a renormalization-group invariant mean-field approach to the Parity-Doublet Model that incorporates baryonic vacuum contributions, enabling a consistent analysis of chiral symmetry restoration in nuclear and neutron-star matter across relevant densities and temperatures.
This paper demonstrates that spacetime curvature in and black hole backgrounds induces an effective magnetic field and chiral chemical potential for Dirac fermions, driving asymmetric real-time transport and entanglement dynamics confined within inhomogeneous Lieb-Robinson cones that are diagnostic of curvature and horizon effects.
This study investigates the impact of octupole deformation on nuclear electromagnetic responses using linear response theory and finds that while the deformation has only a modest effect on resonance transition strengths, strengths are significantly enhanced at low energies and isoscalar responses require the removal of the rotational Nambu–Goldstone mode for accurate analysis.
This paper employs the Configuration Interaction Shell Model to predict photon strength functions for light nuclei (–$40$) and evaluates their impact on the propagation modeling of ultra-high-energy cosmic rays, specifically addressing the needs of the PANDORA project.
This paper benchmarks Variational Quantum Eigensolver (VQE) algorithms against classical exact diagonalization for the deuteron, triton, and helium-3 nuclei within lattice pionless effective field theory, demonstrating that noiseless simulations achieve high accuracy while also quantifying the impact of realistic hardware noise on variational energy estimation.
This paper applies the distribution-free Conformalized Quantile Regression method to Bayesian posterior samples of neutron star mass-radius relations and pure neutron matter calculations to generate reliable, model-agnostic uncertainty bands with guaranteed coverage.
This study utilizes an interacting boson model based on nuclear density functional theory to demonstrate that octupole correlations significantly influence low-lying states and two-neutron transfer intensities in rare-earth nuclei, successfully reproducing the experimental discontinuous changes near or 90 associated with shape phase transitions.
This paper employs Bayesian inference to demonstrate that small-radius compact-star candidates can be explained by a twin-star scenario involving a strong first-order phase transition to quark matter at approximately 2.7–2.8 times nuclear saturation density, characterized by a large energy-density jump and high sound speed, which produces a distinct hybrid branch with radii of 6–7 km and significantly suppressed tidal deformability.
