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.
By embedding Fick-type diffusion into relativistic Fokker-Planck kinetic theory, this paper formulates a well-posed initial-value problem for Lorentz-boosted diffusion that admits exact, closed-form analytic solutions as a discrete superposition of band-limited initial data.
This study presents the first end-to-end simulation demonstrating that the magnetized accretion-induced collapse of a white dwarf produces neutron-rich ejecta capable of robust -process nucleosynthesis, generating a lanthanide-rich kilonova signal that matches the observed properties of AT 2023vfi/GRB 230307A without parameter tuning.
This paper presents a four-dimensional Langevin framework calculation of isotope-resolved Ba and Xe fission yields across various actinides, demonstrating successful reproduction of dominant neutron-number maxima while identifying a systematic tendency for the model to predict narrower distribution tails than observed in evaluated reference data.
Using the Grassmann corner transfer matrix renormalization group, this study maps the phase diagram of the single-flavor Gross--Neveu--Wilson model, identifying critical lines with central charges and that separate the Aoki, topological insulator, and trivial phases, while finding that the Aoki phase does not persist in the strong-coupling regime.
This paper proposes a consistent holographic scheme involving D7-brane rotation to correctly incorporate chiral anomaly contributions in the D3/D7 model, demonstrating that this approach realizes a finite axial chemical potential and enhances negative magnetoresistance.
This study employs ab initio Bogoliubov coupled cluster calculations to demonstrate that current chiral effective field theory interactions fail to simultaneously reproduce the absolute charge radii, parabolic isotopic shifts, and the kink at Sn in the Tin chain, thereby highlighting the need for improved theoretical models and new experimental data to better constrain nuclear forces.
This paper reveals fundamental trade-offs in Gauss's law-based quantum error correction for 1+1D lattice QED, demonstrating that while it can reduce qubit overhead and offer lower single-round error rates, it imposes strict constraints on electric field configurations and ultimately leads to faster decoherence to mixed states compared to universal codes under repeated error correction cycles.
This study demonstrates that hadronic regeneration of mesons from -meson collisions during the hadronic break-up phase in Pb+Pb collisions significantly contributes to the final observed yields, implying that regeneration must be accounted for in models and making it difficult to distinguish between regeneration occurring at hadronization versus during final-state interactions.
This paper theoretically demonstrates the feasibility of observing mesic nuclei via the semi-exclusive C($p, dp$) reaction by utilizing the JAM transport model and Green's function method to show that detecting energetic protons from non-mesic absorption and forward-going deuterons is critically important for identifying bound states.
By combining a hybrid VDF+MIT equation of state with the AMPT-HC transport model and recent experimental directed flow data, this study constrains the hadron-quark phase transition to occur between 5 and 6 times nuclear saturation density and proposes the energy derivative of the mid-rapidity slope as a robust observable for identifying the QCD critical point.
