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 an exact information-geometric equality for single-qubit systems that enables a non-iterative, linear regression approach to continuous-time quantum process tomography, effectively bypassing local minima issues while accurately estimating GKSL master equation parameters.
This paper establishes a general, relativistically covariant theoretical framework for the semi-inclusive deep-inelastic scattering cross section and spin observables on a polarized spin-1 target, expressed in terms of invariant structure functions and valid across all deep-inelastic final-state regions.
This paper develops a light-front theoretical framework for semi-inclusive deep-inelastic scattering on a polarized deuteron with spectator nucleon tagging, deriving tagged structure functions and spin asymmetries that highlight the role of the deuteron's D-wave component and provide essential tools for future experiments at Jefferson Lab and the Electron-Ion Collider.
This paper demonstrates the feasibility of simulating the thermalization dynamics of minimally truncated SU(2) lattice gauge theory on current noisy quantum hardware by successfully matching error-mitigated results from IBM quantum computers with classical simulations for chains of up to 101 plaquettes.
This study employs self-consistent Hartree-Fock + Random Phase Approximation calculations to demonstrate that adding multiple hyperons to closed-shell nuclei systematically increases excitation energies and nuclear incompressibility, with the hyperons' dynamical influence remaining predominantly in phase with protons.
This study presents the most accurate test to date of isospin symmetry in the mass system by utilizing precision Coulomb excitation measurements of Zn, Ga, and Ge at RIKEN to confirm a linear relationship between their proton matrix elements, a finding supported by large-scale shell-model calculations.
This paper demonstrates that in coupled-channel dynamics, the conventional method of assessing a channel's importance by deleting it is misleading because it conflates intrinsic contributions with model-space reorganization, whereas a basis-preserving decoupling approach reveals that the true contribution is better tracked by the dynamic polarization potential and often exhibits quantum anti-synergy.
This study measures the dipole response of the neutron-rich nucleus He, revealing that its low-energy dipole strength is dominated by two-neutron emission rather than four-neutron decay, and provides experimental values for total dipole strength and polarizability that are compared with state-of-the-art theoretical models.
Using a Monte Carlo event generator with -factorization, the study demonstrates that the observed stronger-than-linear growth of D-meson yields in high-multiplicity pp and pPb collisions is reproduced by various initial-state spatial distributions, indicating that this observable is insufficient for distinguishing the specific matter geometry within the proton.
This paper presents a deterministic quantum algorithm that efficiently constructs antisymmetric fermionic states in first quantization mapping using -gates and dirty ancilla qubits, offering a significant performance advantage over sorting-based methods for systems where the particle count is less than the square root of the available orbitals.
