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 establishes a quantitative framework linking local spin polarization and quantum entanglement in two-qubit systems by deriving a closed-form upper bound on concurrence that is saturated by pure states, and demonstrates its application to the process where polarization significantly constrains maximal entanglement.
This paper presents the first application of unbiased exponential resummation to (2+1)-flavor lattice QCD at physical quark masses, yielding consistent determinations of the QCD pseudocritical temperature and curvature coefficient that validate the method as a reliable approach for probing the QCD crossover at small finite baryon density.
This paper reports the discovery and analysis of three rotational glitches in the previously quiet young pulsar PSR J1637$-$4642, observed over a 15-year period, with modeling of the largest event supporting the standard superfluid vortex-creep paradigm and demonstrating that even "quiet" pulsars can exhibit substantial glitch activity.
This paper demonstrates that color triality constraints on vacuum hadronization allow the simultaneous measurement of conserved current flows (electric charge, baryon number, and strangeness) in jets to directly probe nonperturbative QCD parameters, specifically the diquark-to-quark production ratio and strange-to-light pair-production ratio, while satisfying the Gell-Mann–Nishijima relation.
Using the covariant Nambu-Jona-Lasinio model with Schwinger proper-time regularization, this study investigates the skewness and momentum transfer dependence of pion and kaon generalized parton distributions, finding that valence-quark distributions are strongly suppressed by increasing momentum transfer and skewness (especially at lower scales) while gluon distributions show weak dependence on both, with results at specific scales aligning well with experimental data, global JAM analyses, and lattice-QCD calculations.
This paper identifies negative diffusion as the intrinsic cause of numerical instabilities in the Functional Renormalization Group flow of the Quark-Diquark Model at low temperatures and high chemical potentials, and proposes a hyperdiffusion-based regularization scheme to stabilize the flow for reliable studies of color superconductivity and inhomogeneous phases.
This paper demonstrates that while the choice of hydrodynamic frame (Eckart vs. Landau--Lifshitz) significantly alters the numerical values of transport coefficients like thermal conductivity, physical observables such as sound attenuation remain invariant, underscoring the necessity of specifying the frame when comparing results across different theoretical and experimental contexts.
This study demonstrates that, within an idealized three-component framework, the morphology of neutron star glitch rises is sensitive to microphysical inputs like entrainment and mutual friction, allowing high-cadence timing observations of events like the 2016 Vela glitch to potentially constrain the internal dynamics and equation of state of neutron stars.
This paper employs gauge/string duality to model a system, demonstrating that its ground state can manifest as a hadronic molecule, a tetraquark, or a superposition depending on geometry, while also deriving asymptotic energy expressions and confirming the universality of string tension for multiquark configurations.
This paper introduces a GPU-accelerated Filon-type quadrature method that efficiently computes the oscillatory Hankel transforms of multi-Wilson-line correlators required for Color Glass Condensate cross-section calculations, significantly reducing runtime and enabling next-to-leading-order proton-nucleus and electron-ion scattering simulations beyond the correlation-limit approximation.
