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.

Probability distribution of observables from a Bogoliubov vacuum projected onto good particle number: application to scission configurations of an actinide

This paper proposes and validates a method to compute complete probability distributions for fission observables, such as total kinetic energy, by sampling nucleonic configurations from a Bogoliubov vacuum projected onto good particle number, revealing that significant fluctuations in actinide scission are already captured within the mean-field framework.

Origin of the Covariant Wigner Operator as a Quantum Amplitude in QCD

This paper extends the Koopman-von Neumann-Sudarshan Hilbert space formulation to relativistic QCD, demonstrating that the covariant Wigner operator is fundamentally a quantum probability amplitude projected onto phase space, thereby offering a unified framework that clarifies the origin of nonclassical features like negativity and establishes a transparent foundation for parton distribution functions.

Long-standing problem: The nuclear level density angular-momentum dependence and isomeric data assessment

This paper highlights that recent experimental challenges in describing isomeric cross sections for Tc isotopes reveal significant limitations in current nuclear level density models when using standard rigid-body moment of inertia values, thereby underscoring the urgent need for direct measurements of average resonance spacings to validate and improve angular-momentum dependence assessments.

Femtoscopy of Strange Baryons in Heavy-ion Collisions at RHIC-STAR

The STAR experiment at RHIC presents high-statistics femtoscopy results from Isobar and Au+Au collisions, revealing an attractive interaction in $\Xi$ - $p$ pairs and a bound state in $\Omega$ - $p$ pairs through the analysis of final-state correlations.

Collective quantum tunneling with time-dependent generator coordinate method

Inspired by McGlynn and Simenel's work, this study demonstrates that the time-dependent generator coordinate method (TDGCM), utilizing real-time mean-field states as generators, successfully overcomes the spurious self-trapping effect in interacting two-particle tunneling to reproduce exact quantum dynamics while providing critical insights into collective versus single-particle behaviors.

Formal definition of intrinsic collectivity in the continuum via Takagi factorization of the Jost-RPA S-matrix residue

This paper proposes a formal framework utilizing Takagi factorization of the Jost-RPA S-matrix residue to define intrinsic collectivity in continuum resonance states, introducing new indices that reveal hidden collective modes in $^{16}$ O which are decoupled from their observable line shapes.

Shear viscosity and electrical conductivity of rotating quark matter in Nambu--Jona-Lasinio Model

This study utilizes a two-flavor Nambu--Jona-Lasinio model within a kinetic theory framework to demonstrate that finite rotation modifies the transport properties of quark matter by reducing the chiral condensate, inducing anisotropy in shear viscosity and electrical conductivity, and generating significant non-dissipative Hall-like currents at zero net density.

Learning Informed Prior Distributions with Normalizing Flows for Bayesian Analysis

This paper demonstrates that normalizing flow models trained on previous posteriors can serve as effective, flexible priors for sequential Bayesian inference in high-dimensional spaces, provided that target distributions are unimodal and robust sampling algorithms are employed.

Magnetization by Rotation: Spin and Chiral Condensates in the NJL Model

This paper investigates how spin condensates, arising from rigid rotation in the Nambu-Jona-Lasinio model, can counteract the rotational suppression of chiral condensates and potentially shift the chiral phase transition from second to first order.

Many-body correlations as the origin of Gamow-Teller quenching in nuclear $\beta$ -decay

This study demonstrates that many-body nuclear correlations, particularly deformation and cross-shell mixing in heavy open-shell nuclei, are the primary origin of Gamow-Teller quenching in nuclear $\beta$ -decay, driving strength to high excitation energies and overshadowing the modest contribution from chiral two-body currents.
