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 Quantum Chromodynamics in two spacetime dimensions using the Functional Renormalization Group to derive flow equations for gauge and quark parameters, demonstrating a transition from ultraviolet super-renormalizability to a strongly coupled infrared regime while establishing a foundation for future studies of bound state spectra.
Using an open quantum system framework to simulate bottomonium evolution in the quark-gluon plasma, the study reveals that while the medium suppresses quantum nonclassicality, a finite residual quantum structure persists due to the preferential dissolution of weakly bound states, demonstrating that classicalization is partial and observable-dependent.
This paper is a personal and professional retrospective by the author on their thirty-year collaboration with Mannque Rho (1978–2008), highlighting key theoretical contributions such as the Little Bag, the Cheshire Cat principle, and Skyrmion matter.
This paper presents the first microscopic, energy-resolved simulation of spin and parity distributions in Pu fission fragments, revealing their non-monotonic evolution with excitation energy and demonstrating how these distributions predict prompt photon multiplicities without adjustable parameters.
This paper investigates how first-order phase transitions from hadronic to quark matter affect proto-neutron star evolution and concludes that gravitational "twin stars" are only viable if the hybrid star lacks a corresponding baryonic twin, effectively placing most such hybrid branches in the "shadow" of the hadronic branch.
This paper presents a unified ab initio description of superfluid neutron matter across a wide density range using the nonperturbative Gorkov algebraic diagrammatic construction method, successfully quantifying pairing gaps and identifying microscopic signatures of superfluidity while assessing the sensitivity of these results to many-body truncations.
This paper investigates diffractive vector meson production in electron-polarized deuteron collisions at the Electron-Ion Collider, demonstrating how the deuteron's polarization state influences azimuthal angular distributions, effective radius structure, and gluon saturation effects.
This paper surveys legacy and novel "table-top" approaches to nuclear fusion, with a specific focus on aneutronic reaction chains like proton-boron and helium-beryllium cycles, while addressing practical challenges, isotopic constraints, and applications in civilian power and space travel.
This paper proposes a "beyond Landau" syncretic model where the topological charge becomes fractional below the chiral phase transition, leading to fractional powers of the anomalous determinant in the effective Lagrangian and predicting a generically second-order chiral phase transition that can be tested via lattice QCD measurements of meson propagators and quark condensates.
This paper presents a model using fractional anomalous determinants to describe trace and axial anomalies in gauge theory at nonzero , successfully reproducing lattice results for vacuum energy and glueball masses while explaining the observed three-pseudoscalar decay channels of the candidate.
