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.
This paper provides approximate neutrino interaction rates for binary neutron star merger simulations in strong magnetic fields, incorporating Landau quantization and anomalous magnetic moments with controlled errors, while also identifying a low-density neutrino production channel from individual neutrons.
This paper introduces perturbation theory quantum Monte Carlo (PTQMC), a stochastic method that efficiently computes high-order many-body perturbative corrections by using random walkers to avoid exponential scaling, while also providing a new complexity metric () to better assess the validity of perturbative expansions.
This paper presents a Core-Corona model incorporating intrinsic polarization functions derived from a field-theoretical approach with effective mediators, which successfully describes the excitation function of global polarization across the full experimental energy range by highlighting the dominant role of the dilute corona and predicting a robust maximum near GeV.
This paper presents leading-order calculations for forward trijet production in the gluon-initiated channel of proton-nucleus collisions within the Color Glass Condensate framework, identifying specific contributions from four-gluon vertices and rapidity/collinear divergences to validate the dilute-dense hybrid formalism as a crucial step toward complete next-to-leading order analyses.
By combining gravitational wave and X-ray observations, this study infers that neutron star cores likely exhibit sound-speed stiffening above of the speed of light, a regime typically reached by stars with masses around and fully accessed only by the most massive pulsars near .
This paper reviews the successes of the statistical hadronization model in describing hadron production across a broad range of collision energies for both light and heavy quarks, while highlighting recent findings on QCD phase structure and identifying remaining open issues.
This paper investigates the systematics of pygmy dipole resonances in neutron-rich medium-heavy and heavy nuclei by applying a modified macroscopic Isacker-Nagarajan-Warner model that links resonance energy to neutron skin thickness, demonstrating good agreement with experimental and microscopic data while suggesting that the required neutron-proton interaction strength challenges the notion of PDR as a purely collective state.
This paper completes the study of relativistic spatial distributions of the energy-momentum tensor in polarized nucleons by focusing on transverse components and their multipole structure, demonstrating that the quantum phase-space formalism reproduces standard light-front distributions in the infinite-momentum frame.
This paper formulates a fluctuating hydrodynamics with spin that is both generally covariant and pseudo-gauge invariant by extending the Gaussian covariant approach using torsion as an auxiliary field and deriving second-order gravitational Ward identities in the torsionful case.
This paper theoretically investigates the interaction of an antikaon with a Li nucleus modeled as an cluster system to predict quantitative signatures of the resonance in low-energy dynamics, providing crucial guidance for future experimental searches in the absence of dedicated data.
