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 extends neural-network quantum states to solve strongly interacting few-body problems in continuous space, successfully computing Efimov states and reproducing their key physical features for systems ranging from three to six identical bosons and mass-imbalanced fermions.
This paper investigates boost-invariant spin hydrodynamics with a first-order framework, demonstrating that spin dissipation alters the temperature evolution of the expanding medium and subsequently enhances thermal dilepton production, thereby suggesting dileptons as a viable probe for spin dynamics in the quark-gluon plasma.
This paper investigates how fermionic dark matter interacting with nucleons via a vector mediator () alters the equation of state and structural properties of neutron stars, demonstrating that observational constraints on mass, radius, and tidal deformability can limit vector portal parameters while linking astrophysical findings to terrestrial dark matter searches.
This paper demonstrates that the nucleus Er exhibits rigid triaxiality with a deformation angle of rather than a prolate shape, a conclusion supported by the SU(3)-IBM framework including higher-order interactions which accurately reproduces experimental energy spectra, transition strengths, and quadrupole moments.
This paper reviews the application of the ab initio no-core shell model with continuum (NCSMC) approach, utilizing chiral nuclear forces to unify the description of bound and unbound states in light halo nuclei such as He, B, Be, and C, while also addressing challenges in modeling Borromean systems and presenting preliminary studies on Be and Li.
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 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 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.
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 highlights that recent experimental challenges in describing isomeric cross sections for Tc isotopes reveal significant limitations in current nuclear level density models when using standard rigid-body moment of inertia values, thereby underscoring the urgent need for direct measurements of average resonance spacings to validate and improve angular-momentum dependence assessments.
