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?

Below are the latest papers in nuclear theory, distilled and ready for you to explore.
Using three-dimensional tilted axis cranking covariant density functional theory, this study reveals the coexistence of magnetic and chiral rotational modes built on identical quasiparticle configurations in and , establishing a new type of shape coexistence and uncovering a distinctive rotational mode transition from principal-axis to planar and finally to chiral rotation as frequency increases.
This paper proposes utilizing the Electron-Ion Collider to test quantum entanglement and Bell nonlocality by analyzing spin correlations in quark-antiquark pairs produced via photon-gluon fusion, highlighting the facility's cleaner environment and strong signal potential for verifying these quantum phenomena compared to hadron colliders.
This paper establishes a rigorous general relativistic framework for the dynamical tides of binary neutron stars using matched-asymptotic expansions, proving that their response can be modeled by a complete set of modes satisfying a forced harmonic oscillator equation to prevent systematic biases in future gravitational-wave parameter estimation.
This article provides a comprehensive overview of eighty years of experimental and theoretical research on meson production, tracing the field's evolution from the initial discovery of the pion to modern studies involving charm and beyond, which have been fundamental to understanding hadrons, low-energy QCD dynamics, and the Standard Model.
This paper calculates the tensor-polarized twist-3 parton distribution function for the spin-1 deuteron by applying twist-2 relations to the known twist-2 function , demonstrating that is comparable in magnitude to and suggesting that current and future facilities like JLab and the EIC are well-suited to investigate these higher-twist effects.
This paper presents a data-guided coalescence model that successfully predicts light nuclei and hypernuclei production across a wide energy range in relativistic heavy-ion collisions, revealing that hypertriton yields are highly sensitive to wave function assumptions, particularly at low energies and in low-multiplicity environments.
This paper reports the existence of a hydrodynamic attractor in Mueller-Israel-Stewart fluid dynamics within Grozdanov's novel hyperbolic geometry, demonstrating that late-time hydrodynamization occurs rapidly even with a large Knudsen number because the inverse Reynolds number remains small as shear stress vanishes.
This paper constructs a neutron model analogous to a classical proton model to demonstrate that, despite electromagnetic-induced divergences at extremely small momentum transfers, the energy-momentum tensor form factor of protons and neutrons remains practically indistinguishable across experimentally accessible ranges, thereby accurately explaining the nucleon mass difference and reproducing lattice QCD data.
Using continuum Schwinger function methods, this paper demonstrates that the pion and kaon possess significant intrinsic orbital angular momentum in their rest frames and light-front projections, revealing them as complex bound states with observer-dependent OAM compositions that must be accounted for in hadronic observables.
This paper presents the first lattice-QCD estimate of the QCD crossover line down to MeV by introducing a novel method that combines Lee-Yang edge singularities from imaginary chemical potential simulations with universal chiral scaling to determine the baryon chemical potential dependence of critical temperatures without relying on small- expansions.
