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 parameter-free method to determine the chiral phase transition temperature and critical exponent in (2+1)-flavor QCD by constructing ratios of an improved, renormalized order parameter, with initial numerical results obtained on lattices using staggered fermions.
NuLattice is a Python software package that enables ab initio computations of light atomic nuclei on lattices using methods like Hartree-Fock and coupled cluster theory with pion-less effective field theory interactions, allowing such calculations to be performed on standard laptops.
By combining quasi-elastic scattering measurements with coupled-channels and shell-model calculations, this study reveals that while Si has a distinct oblate ground state, the addition of two neutrons in Si leads to a sudden structural change where the nucleus lacks a well-defined intrinsic shape, suggesting the presence of ground-state shape fluctuations.
This paper discusses the various roles of strong electromagnetic fields generated in relativistic heavy-ion collisions, highlighting the need for theoretical and experimental advancements to better understand quark-gluon plasma dynamics and ultraperipheral electromagnetic processes.
This paper presents the first extension of the Many-Body Forces (MBF) Model to finite temperature, introducing new hyperon coupling schemes to analyze the thermodynamic properties of beta-equilibrated nuclear matter and the mass-radius relations of compact stars, thereby establishing a new framework for describing proto-neutron stars.
This paper resolves the hyperfine puzzle in hydrogen, which suggests a variational collapse due to a energy term, by demonstrating that accounting for the proton's finite size yields a stable ground state with a radius indistinguishable from the Bohr radius.
This paper investigates the phase-space properties of parity-adapted U()-spin coherent states to analyze quantum phase transitions in -quDit systems, demonstrating that their Husimi functions, moments, and Wehrl entropy serve as effective localization measures for visualizing critical precursors in the -level Lipkin-Meshkov-Glick model.
This paper extends spherical coupled-cluster theory to open-shell nuclei with two nucleons removed, validating the method against experimental data for oxygen and calcium isotopes while demonstrating high accuracy for binding energies and excited states but noting an underestimation of electric dipole polarizabilities.
This paper extends the pion-nucleus multiple-scattering framework to include second-order rescattering dynamics and nuclear structure details derived from chiral effective field theory, demonstrating that these corrections are essential for accurately reproducing differential cross sections in -Ca elastic scattering within the -resonance region.
This paper presents ab initio calculations of the electric dipole polarizability for the neutron-rich isotope O using the Lorentz integral transform coupled-cluster approach with chiral two- and three-nucleon interactions, finding good agreement with experimental data in the low-energy region.
