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 investigates hybrid stars by employing a smooth switching function to model the hadron-to-quark matter transition, systematically analyzing the role of symmetry energy and constraining model parameters to create a physically motivated framework capable of predicting the properties of low-mass, small-radius compact objects.
This paper employs a species-resolved anisotropy-response scaling framework to demonstrate that -meson elliptic and triangular flow in heavy-ion collisions deviate from light-flavor scaling due to charm-specific attenuation, quantified by a collision-energy and centrality-dependent rescaling factor and a small hadronic-rescattering correction, thereby providing new differential benchmarks for heavy-quark transport and medium evolution.
This paper investigates the Nambu-Jona-Lasinio model under rigid rotation to demonstrate that while rotation typically suppresses the chiral condensate, the emergence of a spin (axial-vector) condensate can counteract this suppression, potentially enhancing the chiral condensate and shifting the chiral phase transition from second to first order.
This paper presents closed-form Pfaffian and minor formulas for calculating norms and density matrices in number-conserved pairing theory for both even and odd systems, which are then applied to angular-momentum-projected BCS calculations of Ge and Ge to interpret their low-lying collective bands.
This thesis advances the theoretical and statistical toolkit for searching for light dark matter (MeV–GeV) at fixed-target experiments like LDMX and SHiP by developing comprehensive frameworks for model building, likelihood-based inference, global fits, and improved signal simulations that incorporate advanced nuclear modeling.
This paper presents a new set of hybrid star equations of state (SmallQ) that relaxes the requirement for maximum-mass neutron stars to have large quark cores, resulting in models with higher phase transition densities, smaller radii, and improved compatibility with NICER and GW190817 observations compared to previous constraints.
This paper derives a generalized Fano formula within the Jost-random-phase approximation framework to explain how interference between resonance poles and background continua produces diverse spectral patterns—including Breit-Wigner peaks, Fano dips, and Fano-type peaks—in O and Pb, demonstrating that these features depend on the alignment of transition amplitudes rather than standard collectivity indicators.
This paper presents ab initio-guided nonlocal optical potentials for semi-magic nuclei by extending Gorkov self-consistent Green's function theory to open-shell targets and proton projectiles, demonstrating reasonable agreement with scattering data at forward angles while identifying the need for larger model spaces to better reproduce backward-angle absorption.
This paper introduces a thermal double particle-number projection formalism based on the Balian-Brezin representation to explain the quantum-thermal interplay governing particle and energy sharing between entangled fission fragments, successfully resolving the puzzling energy dependence of odd-even staggering in charge yields and sawtooth neutron multiplicities in 240Pu fission.
This paper proposes an information-theoretic oscillator framework to derive negative binomial and generalized negative binomial distributions for modeling multi-particle production, demonstrating that the latter effectively describes high-multiplicity data and introducing a novel Lerch-type generalization of the Barnes zeta function for non-degenerate systems.
