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 demonstrates that the Superfluid -Cluster Model, by rigorously treating Nambu-Goldstone zero modes, provides a unified description of low-spin six- condensate states and high-spin C()+C() molecular resonances in Mg, identifying these states as a signature of nuclear supersolidity characterized by the coexistence of superfluidity and crystallinity.
This paper introduces a novel virtual rishon framework that enforces gauge symmetry via intermediate quantum-link representations to enable scalable simulations of lattice gauge theories in d+1 dimensions using both classical tensor networks and near-term quantum hardware, validated by benchmarking on the multi-flavor Schwinger model and 2D string tension.
This paper presents a simultaneous analysis of measured and calculated data to predict the prompt fission neutron spectra (PFNS) of 233U(n,F) up to 20 MeV, establishing that while its spectrum is harder than 235U(n,F) but softer than 239Pu(n,F), the underlying pre-fission contributions and energy partitioning differ significantly due to fissility and competing reaction channels.
This paper utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
This paper investigates the impact of strongly-interacting dark matter, modeled by a first-principles QCD-like gauge theory, on neutron star structure and confirms that such dark matter can be accommodated within current observational constraints.
This paper challenges the interpretation of the nucleon's momentum current density as a continuous medium's pressure and shear forces, arguing instead that color interactions are long-ranged and that only the isotropic vacuum pressure term derived from the QCD trace anomaly effectively provides the confining potential for quarks.
This paper demonstrates that including twist-four kinematic power corrections modifies the subtracted constants in deeply virtual Compton scattering dispersion relations, causing the helicity-conserving amplitude to depend on double distributions in addition to the -term, a mixing effect that significantly impacts the extraction of pressure forces from Jefferson Lab data.
This paper demonstrates that kinematic power corrections in deeply virtual Compton scattering dispersion relations provide a novel experimental constraint on nucleon momentum, pressure, and total angular momentum distributions, with continuum and lattice-QCD predictions indicating that momentum distributions account for approximately one-third of the signal at .
This paper presents the first next-to-leading-logarithmic QCD analysis of electromagnetic corrections to the semileptonic weak Hamiltonian, calculating mixed corrections to the vector coupling to yield a refined radiative correction value that enhances the consistency of first-row CKM unitarity tests.
This paper introduces a new universality paradigm for hybrid qubit-qumode quantum computing based on trigonometric continuous-variable gates, demonstrating their effectiveness through a deterministic ancilla-based implementation and a successful simulation of the lattice sine-Gordon model, including ground state preparation, real-time dynamics, and kink profile extraction.
