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 demonstrates that the accumulation of states in various rare earth nuclei can be microscopically explained using the pseudo-SU(3) model, highlighting the essential role of the Pauli Exclusion Principle and the microscopic Hilbert space in understanding these spectra.
This paper investigates how different treatments of mass loss and convective overshooting influence the pre-collapse core properties and neutrino emission of red supergiants, demonstrating that these factors significantly alter the star's thermal structure, isotopic composition, and the resulting neutrino spectra in the final days before collapse.
This review examines how extreme magnetic fields in magnetars influence the microscopic properties of dense fermionic matter and the resulting macroscopic structure and composition of compact stars.
This paper presents a Regge exchange model analysis of high-energy polarized photoproduction data from GlueX and SLAC, using spin density matrix elements to constrain helicity amplitudes and providing the first extractions of several meson-nucleon-delta coupling constants.
This paper presents converged *ab initio* calculations of short-range neutrinoless double-beta decay nuclear matrix elements for key isotopes using chiral effective field theory and the in-medium similarity renormalization group, ultimately using these results to constrain the parameter space for a fourth sterile neutrino.
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.
