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.
The STAR experiment at RHIC presents high-statistics femtoscopy results from Isobar and Au+Au collisions, revealing an attractive interaction in - pairs and a bound state in - pairs through the analysis of final-state correlations.
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.
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 O which are decoupled from their observable line shapes.
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.
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.
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.
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 -decay, driving strength to high excitation energies and overshadowing the modest contribution from chiral two-body currents.
This paper reviews the current state of the QCD phase diagram by synthesizing insights from lattice simulations, effective field theories, and chiral models to reconstruct the full phase structure for physical quark flavors and constrain matter properties in neutron star cores.
This paper presents a first-principles, non-perturbative study of quantum entanglement among partons in a strongly coupled scalar Yukawa theory using light-front Hamiltonian methods, revealing that while entanglement in the quenched limit relates to classical Shannon entropy, the unquenched framework exhibits genuine non-classical correlations that encode quantum information beyond classical probabilities.
Using light-front holographic QCD, this paper demonstrates that the nucleon's gravitational form factor is significantly suppressed at finite momentum transfer due to a fundamental cancellation arising from an antisymmetric factor in the longitudinal dynamics, which serves as a signature of the nucleon's dominant S-wave character.
