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 demonstrates that generalized higher-form symmetries, exemplified by axion electrodynamics, drive a novel self-similar inverse cascade that organizes non-equilibrium turbulent systems into large-scale coherent structures through universal scaling behavior.
This paper presents a perturbative framework within chiral effective field theory that solves a hierarchy of integral equations to calculate nucleon-deuteron elastic scattering observables up to next-to-leading order, offering a renormalization-group invariant alternative to direct distorted-wave evaluations.
This paper computes charm and strange meson fragmentation functions by deriving and solving a set of twenty-five coupled jet equations based on Poincaré covariant Bethe-Salpeter wave functions, thereby providing a consistent description of quark hadronization across both light and heavy sectors.
This paper establishes a covariant framework for semi-classical spin hydrodynamics in flat and curved spacetimes, demonstrating that spin and fluid modes decouple in the linear regime with damping governed solely by spin relaxation coefficients, while also highlighting the limitations of the Gibbs stability criterion due to equilibrium anisotropy and confirming similar relaxation dynamics in a conformal Bjorken flow background.
This paper provides a systematic derivation for graduate students and researchers in nuclear physics, transforming the three-body Schrödinger equation from single-particle coordinates to Jacobi and hyperspherical coordinates while explicitly calculating Jacobian determinants and projecting the resulting Faddeev equations onto a hyperspherical harmonics basis to obtain coupled hyperradial equations.
This study demonstrates that future high-precision radius measurements of neutron stars will significantly constrain the hadron-quark phase transition density and related equation of state parameters through Bayesian analysis, yet will remain largely insensitive to the stiffness of quark matter regardless of measurement accuracy.
This paper utilizes an effective theory of dynamic critical phenomena to demonstrate that the photon emission rate near the QCD critical point diverges with the correlation length and follows a universal spectrum, reflecting the nonequilibrium properties of the near-critical liquid.
This paper applies a tractable -matrix model to investigate the nuclear reaction processes, fusion rates, and sticking probabilities of the muonic molecule, specifically analyzing -wave fusion channels and charge symmetry violations in light of recently reported discrepancies in -wave astrophysical factors.
This paper presents a unified framework within the X-SCAPE code that utilizes the SMASH transport model to generate event-by-event initial conditions for hydrodynamic simulations of heavy-ion collisions at finite densities, incorporating a 4D lattice-QCD equation of state and generalized out-of-equilibrium corrections to study conserved charge fluctuations in the Beam Energy Scan program.
This paper validates a time-dependent coupled-cluster theory approach for computing nuclear response functions by demonstrating its accuracy against static frameworks and revealing collective dipole resonances and chaotic behavior in light nuclei under strong electric fields.
