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.

Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper demonstrates that recycling a single ancilla qubit through mid-circuit measurement and reset reduces the active qubit requirement for rodeo filtering in trapped neutron-proton scattering simulations from 12 to 3, achieving a 75% hardware compression while maintaining accuracy comparable to static implementations.
This paper investigates the electromagnetic screening properties of fermionic domain-wall Skyrmions within the chiral soliton lattice of two-flavor QCD under a strong magnetic field, utilizing moduli effective theory and finite-temperature chiral perturbation theory to characterize baryon density saturation and predict static screening via a combined Debye mass.
This paper demonstrates that artificial confinement methods using harmonic-oscillator traps, spherical hard walls, and periodic boxes can consistently extract coupled-channel scattering observables, including phase shifts and inelasticity, for the He system with and without Coulomb interactions, thereby providing a controlled benchmark for future ab initio reaction calculations.
This paper introduces a Direct Boundary Matching Method (DBMM) that solves nuclear scattering problems, including coupled-channel cases, by incorporating outgoing wave boundary conditions directly into a Lagrange-Legendre matrix formulation, thereby eliminating the need for Bloch operators or complex coordinate scaling while achieving accuracy comparable to traditional Numerov integration.
This study demonstrates that nuclear responses to two-body external fields in 16O and 40Ca require a fully microscopic Second Random-Phase-Approximation treatment of 2p2h mixing, as simple folding of one-body responses fails to capture the significant energy shifts and strength redistributions observed in double-phonon excitations.
This paper investigates the spectroscopy and seniority properties of lead isotopes 211, 213, and 215, specifically comparing energy splittings and isomeric states for valence neutrons in the g9/2 shell while also considering configurations beyond this shell.
This paper employs cluster effective field theory to analyze N -delayed decay spectra and -C scattering data, revealing that while the spectra are individually compatible with a common strong continuum, they cannot be simultaneously reproduced by a single minimal weak-current amplitude, thereby highlighting specific experimental and model sensitivities for future unified analyses of the CO reaction.
This paper demonstrates that in the outer cores of neutron stars, locally attractive couplings between neutron superfluids and proton superconductors can lead to the formation of "fluxtube bouquets" where multiple magnetic fluxtubes bind to a single neutron vortex, and confirms the existence of a type-1.5 regime characterized by short-range repulsive and intermediate-range attractive interactions that drive fluxtube clustering even in the absence of phase-gradient entrainment.
This paper develops a systematic effective field theory framework to rigorously separate Standard Model nuclear effects from potential new physics in isotope shift measurements, revealing that the commonly used term arises only at second-order perturbation theory and deriving a long-range potential from nuclear polarizability to enable more precise tests of King non-linearity and nuclear structure.
This paper proposes a novel space-time description of proton structure using impact-parameter Ioffe-time distributions, which enables the first lattice QCD calculation of Ioffe-time-dependent mean squared proton radii and the subsequent extraction of the Compton form factor.
