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.

Microscopic optical potential framework applied to neutron scattering on deformed 48,50^{48,50}Cr

This paper presents a unified microscopic framework based on a symmetry-restored multi-excitation generator coordinate method to derive non-local optical potentials from an effective Hamiltonian, successfully applying it to calculate neutron scattering cross sections for deformed chromium isotopes while consistently treating nuclear structure and reaction observables.

Observation of a dynamic magneto-chiral instability in photoexcited tellurium

Using time-domain terahertz emission spectroscopy, researchers observed a dynamic magneto-chiral instability in photoexcited tellurium, where an electric current parallel to a magnetic field amplifies electromagnetic waves, offering a promising mechanism for THz-wave amplification in chiral materials.

Initial-state geometry and multiplicity distributions in pp and pPb collisions

This study utilizes Monte Carlo simulations based on the Color Glass Condensate formalism to demonstrate that multiplicity distributions in proton-proton and proton-lead collisions can distinguish between different initial-state proton geometries, specifically testing the three-quark Y-shape baryon junction model, while highlighting the critical importance of accounting for intrinsic saturation scale fluctuations.

NJL-Chiral Soliton and the Nucleon Equation of State at supra-saturation density: Impact of Chiral Symmetry Restoration

This paper proposes a method to construct the equation of state for supra-saturation density nuclear matter by modeling nucleons as topological solitons within a bosonized Nambu-Jona-Lasinio framework, demonstrating that the dynamical restoration of chiral symmetry leads to a stiffened equation of state compatible with neutron star observations.

Medium separation scheme effects on the magnetized and cold two-flavor superconducting quark matter

This study demonstrates that applying the Medium Separation Scheme (MSS) alongside Magnetic Field Independent Regularization (MFIR) to the Nambu--Jona-Lasinio model of magnetized two-flavor color superconducting quark matter eliminates unphysical oscillations and ensures positive magnetization, thereby correcting artifacts found in traditional approaches that fail to properly separate medium effects from vacuum contributions.
