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 employs a Bayesian framework with a two-dimensional Gaussian process to quantify chiral effective field theory uncertainties in the equation of state for asymmetric nuclear matter up to twice saturation density, thereby constructing consistent models for the inner crust and outer core of neutron stars.
This paper derives a general formula for the energy level contributions of nuclear tensor polarizability in two-body bound systems, demonstrating its role in mixing states of different orbital angular momenta, and specifically evaluates these effects on the hyperfine structure and S-D mixing in muonic deuterium.
This paper demonstrates that the proposed method of reconstructing the Schrödinger wave function from a discrete superposition of real classical action branches fails in classically forbidden regions and for global phase phenomena, as these quantum effects fundamentally require non-vanishing quantum potentials, complex-valued actions, or global boundary conditions that local real classical trajectories cannot provide.
This paper presents a rigorous theoretical proof of the Strutinsky energy theorem, which clarifies the interpretation of shell-correction decomposition and establishes a foundational framework for constructing nuclear density functionals.
This paper proposes a hybrid coarse-graining model that combines dynamical transport and thermal cluster production to predict light nuclei yields, spectra, and elliptic flows in semi-peripheral Au+Au collisions at 1.23 A GeV, effectively bridging nucleon and cluster descriptions at freeze-out while accounting for thermal non-uniformity and collective transport.
This paper reports the first measurement of the state lifetime in Sn using thermal-neutron capture, where the observed enhanced transition strength provides compelling evidence for multiple shape coexistence, a finding corroborated by theoretical calculations predicting three distinct nuclear shapes in the Sn isotopes.
This paper introduces a novel method that utilizes linear stability analysis in highly boosted frames, exploiting a phenomenon called "-suppression," to efficiently derive necessary causality conditions for relativistic hydrodynamic systems while remaining within the low-energy regime.
This paper proposes that ultraheavy nuclei could constitute the highest-energy cosmic rays, offering a consistent explanation for the Amaterasu particle, constraints on source energy generation rates, and the spectral tension between Telescope Array and Pierre Auger Observatory data, while predicting distinct shower maximum depths for future experimental verification.
Using Faddeev equations in configuration space, this study demonstrates that the large binding energy of the system arises from the short-range behavior of strong attractive potentials, while revealing that the Coulomb interaction has only a marginal perturbative effect on the system's spatial configuration and binding energy.
This paper establishes quasi-universal relations linking the trace anomaly profile in neutron stars to their macroscopic properties, utilizing observational data from specific pulsars and multimessenger constraints to estimate the central trace anomaly of a canonical neutron star.
