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 finite-temperature neutron stars with quarkyonic crossover cores admixed with axions, finding that while temperature has a marginal effect on mass, the significant concentration of axions in the central region substantially alters the star's mass, radius, and deformability.
This paper applies catastrophe theory to analyze the mass-radius topology of hybrid stars, demonstrating how a single first-order phase transition between nuclear and quark matter governs the emergence and stability of different compact star branches through bifurcation structures.
This paper investigates how first-order phase transitions in accreting proto-neutron stars generate simultaneous gravitational waves in the kHz and MHz bands alongside a delayed neutrino burst, offering a unique multi-messenger signature to constrain nuclear matter and phase transition physics.
This paper presents a Bayesian study that incorporates direct Urca cooling constraints into neutron star equation of state inference, revealing that while these composition-sensitive observations have a minor impact on macroscopic properties like mass and radius when combined with other data, they significantly refine our understanding of the proton fraction within neutron stars.
By employing microscopic density distributions from three-dimensional lattice covariant density functional theory, this study demonstrates that accurately describing deformation-sensitive observables in relativistic heavy-ion collisions requires precise control over both the nuclear structure of the deformed uranium nuclei and the density of the reference gold nucleus.
This paper presents exact analytical solutions to the nonlinear relativistic Boltzmann equation for homogeneous, isotropic, massless multicomponent systems, identifying three distinct solution classes for two-component systems that include a novel hybrid structure featuring a non-equilibrium Maxwell-Jüttner distribution coupled with nontrivial dynamics.
This paper analyzes the eigenvectors of the 48Ca nucleus under various quadrupole-type two-body interactions to demonstrate that information entropy and complexity measures clearly distinguish between regular and chaotic nuclear states.
This study demonstrates that while both rope hadronization and hydrodynamic evolution can describe certain aspects of strangeness production in heavy-ion collisions, only the hydrodynamic approach successfully reproduces transverse dynamics, indicating that simultaneously constraining both strangeness yields and transverse flow is essential to distinguish between thermal and non-thermal mechanisms.
This paper introduces version 2.0 of FETA, a modular and flexible Python package that wraps the LLNL-developed YAHFC Hauser-Feshbach code to simulate prompt fission fragment decay, validated through neutron-induced fission of 239Pu.
This paper presents extensive gamma-ray spectroscopy of neutron-rich nuclei between Ni and Sn using the MINOS target system, revealing persistent deformation beyond N=60, erosion of the N=50 shell closure near 78Ni, and providing a theoretical analysis of collective effects in Ge isotopes via the projected generator coordinate method.
