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.

Nonlinear causality of Israel-Stewart theory with diffusion

This paper establishes the first fully nonlinear causality constraints for Israel-Stewart theory with energy and number diffusion in 3+1 dimensions, revealing distinct physical behaviors in Landau and Eckart frames that are missed by linearized approaches and demonstrating that these constraints allow for spacelike baryon currents in the Landau frame while preserving the dominant energy condition in the Eckart frame.

Thermoelectric coefficients of two-flavor quark matter from the Kubo formalism

This study utilizes the Kubo formalism and the Nambu–Jona-Lasinio model to calculate the thermopower and Thomson coefficients of two-flavor quark matter, revealing that these thermoelectric coefficients increase linearly with temperature and decrease with chemical potential, thereby estimating the electric fields generated by thermal gradients in heavy-ion collisions.

Renormalization Group Evolution for In-medium Energy Correlators

This paper presents a first-principles analysis of the renormalization group evolution of two-point energy-energy correlators in light-quark and gluon jets propagating through nuclear matter using the SCETG_{\rm G} opacity expansion, deriving medium-induced corrections to anomalous dimensions and demonstrating the potential of these observables to probe quark-gluon plasma dynamics in small collision systems like pp-Pb and O-O.
