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 utilizes a configuration-mixing Bose-Fermi model and a novel differential charge-radius polarization observable to demonstrate how an unpaired proton in yttrium isotopes (Y) modifies the abrupt collective structural evolution near , revealing a localized core deformation and a transition from weak to strong coupling.
This study investigates the Coulomb and nuclear polarization of nucleon density in the Ca + Pb system using a deformed Woods-Saxon mean field, revealing that the repulsive Coulomb tidal field dominates the induced oblate deformation while the attractive nuclear field partially counteracts it at small separations, with polarization energy primarily driven by dipole rather than quadrupole effects.
This study concludes that while negatively charged kaon condensation can explain the low mass and small radius of the central compact object in HESS J1731--347, it fails to simultaneously account for its observed high surface temperature because the phase transition causes rapid cooling that results in temperatures far below the inferred range.
This paper demonstrates that statistical data assimilation can effectively estimate the amplitude of matter density fluctuations in solar and core-collapse supernova models by analyzing neutrino flavor evolution, with the method showing particular reliability in solar scenarios.
This paper projects that next-generation gravitational-wave observatories like the Einstein Telescope and Cosmic Explorer will enable hundreds of multi-messenger binary neutron star detections annually, allowing for precise constraints on the neutron star equation of state, mass distribution, and cosmological parameters through joint hierarchical Bayesian inference.
This paper presents a quantum signal processing algorithm for the overlap fermion Hamiltonian that preserves the Ginsparg-Wilson relation with controllable error, offering a nearly free quantum simulation of chiral symmetry with logarithmic overhead compared to the Wilson-Dirac Hamiltonian and reduced qubit costs relative to domain-wall fermions.
This study employs the phase function method to reconstruct -- scattering wavefunctions and, after incorporating Pauli exclusion effects via the resonating group method, validates a double Gaussian interaction model that accurately reproduces the resonance energy and scattering parameters while identifying two Pauli-forbidden states.
This paper derives a unified parton shower from effective kinetic theory that consistently describes both high-energy jet quenching and thermal equilibration, enabling the study of jet-medium interactions and hydrodynamic responses like wakes and Mach cones.
This study utilizes a Skyrme-type interaction constrained by double- hypernuclei and neutron star data to demonstrate that multi- hypernuclei are particularly effective for isolating the role of repulsive -wave interactions near normal density, while density-dependent terms remain more critical for high-density neutron star environments.
This paper proposes that the higher angular moments of a jet wake's energy flux serve as a unique spectroscopic probe for detecting non-hydrodynamic modes in the quark-gluon plasma, offering a direct link between microscopic non-equilibrium dynamics and observable detector images.
