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 investigates Quantum Electrodynamics in two-dimensional de Sitter space, demonstrating how cosmological expansion drives the system through a pseudo-critical spectral region that governs the loss of adiabaticity, excitation growth, and the emergence of an irreversibility front detectable via local observables.
This paper reviews the role of spin, magnetic fields, and nucleonic superfluidity in the interior physics of compact stars, utilizing a meta-modeling framework to connect microscopic interactions with macroscopic observables while addressing unresolved dynamics such as vortex lattices, pulsar glitches, and potential quark deconfinement.
This paper critically examines the origins of common recoil-order approximations in traditional -decay formalisms, which have become a limiting factor in precision Standard Model tests due to recent advances in nucleon-level radiative corrections, while addressing resolved issues and identifying open questions in the context of progress in ab initio nuclear theory.
This paper revises the Rhoades-Ruffini bound by relaxing assumptions about the onset of stiff non-nucleonic matter, demonstrating that the theoretical maximum mass of neutron stars could reach or higher and providing a fit formula for this limit based on the speed of sound and transition density.
This study predicts the existence of deformed -wave neutron halos in silicon isotopes Si by integrating deformed relativistic Hartree-Bogoliubov theory with Glauber model reaction analyses, supported by consistent evidence from multiple structural criteria and reaction observables.
This paper proposes and validates a method to compute complete probability distributions for fission observables, such as total kinetic energy, by sampling nucleonic configurations from a Bogoliubov vacuum projected onto good particle number, revealing that significant fluctuations in actinide scission are already captured within the mean-field framework.
By identifying quasi-periodic oscillations in FRB 20240114A as neutron star crustal torsional modes and incorporating nuclear matter constraints, this study estimates the source's mass and radius to be approximately 1.00–1.76 and 13 km, respectively, while simultaneously constraining the nuclear symmetry energy slope parameter to 59.5–96.8 MeV.
This paper extends the Koopman-von Neumann-Sudarshan Hilbert space formulation to relativistic QCD, demonstrating that the covariant Wigner operator is fundamentally a quantum probability amplitude projected onto phase space, thereby offering a unified framework that clarifies the origin of nonclassical features like negativity and establishes a transparent foundation for parton distribution functions.
This paper formulates a covariant mechanical equilibrium condition for the magnetized quark-hadron mixed phase boundary by applying relativistic thin-shell formalism to derive generalized Young-Laplace conditions that replace the standard scalar pressure-balance assumption with a geometry-dependent description of stress-energy conservation.
This paper demonstrates that the analytic structure of partonic calculations for transitions, including anomalous thresholds arising from triangle topologies, fully matches the expectations from hadronic degrees of freedom, thereby validating the use of perturbative operator product expansions to constrain nonlocal charm-loop effects in rare -meson decays.
