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.
Using light-front holographic QCD, this paper demonstrates that the nucleon's gravitational form factor is significantly suppressed at finite momentum transfer due to a fundamental cancellation arising from an antisymmetric factor in the longitudinal dynamics, which serves as a signature of the nucleon's dominant S-wave character.
This study employs a hybrid TDCDFT+GEMINI approach to demonstrate that nuclear de-excitation is essential for reconciling theoretical cross sections with experimental data in multi-nucleon transfer reactions and significantly degrades the initial quantum entanglement between reaction fragments.
This paper proposes that the resonance is a dynamically generated state arising from meson-baryon interactions, analogous to the , with properties consistent with current experimental data.
This paper refines theoretical predictions for light-by-light scattering by improving two-loop helicity amplitudes with asymptotic expansions and Coulomb resummation, providing state-of-the-art Standard Model cross-section calculations and a new Monte Carlo event generator named LbLatNLO.
This paper proposes and validates two quantum algorithms—imaginary-time simulation of Hermitian systems and real-time simulation of non-Hermitian systems—that overcome fast oscillatory behavior in scattering phase shift extraction by utilizing block encoding and Hadamard tests to handle non-unitary evolution without mid-circuit measurements.
This paper introduces an improved, composition-dependent nuclear metamodel for neutron star equations of state that enforces causality at high densities to reduce discarded models and enable Bayesian inference of complex composition-dependent properties like the dUrca threshold and g-mode stability.
This paper extends the IdylliQ model of Quarkyonic Matter to non-zero temperatures by developing a consistent statistical mechanics framework that accounts for simultaneous Pauli exclusion constraints on baryons and quarks, revealing that these constraints reduce available states, factorize the distribution function, necessitate a revised entropy definition satisfying the third law, and cause physical temperature and chemical potential to diverge from their Lagrange multipliers.
This paper investigates the space-time evolution of fluid acceleration in heavy-ion collisions using AMPT and UrQMD models, revealing that peak proper accelerations reach hundreds of MeV with distinct transverse and longitudinal behaviors that may significantly impact QGP physics through effects like the Unruh phenomenon and spin polarization.
This paper presents continuum-estimated (2+1)-flavor lattice QCD results demonstrating that the baryon-electric charge correlation serves as a sensitive magnetometer for strong magnetic fields, while also mapping the equation of state up to and constructing detector-compatible observables to bridge theoretical predictions with experimental heavy-ion collision data.
Using the parity doublet model, this paper demonstrates that gravitational waves from the nuclear liquid-gas phase transition in QCD could produce detectable signals in the millihertz to nanohertz bands, whereas those from the chiral phase transition are too weak to be observed, thereby linking the chiral invariant mass to potential gravitational wave signatures of nucleon mass origins.
