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 proposes a nuclear molecule model for heavy nuclei composed of two interacting heavy nuclei, deriving a Hamiltonian to analytically and numerically describe roto-vibrational excitations in Pu and predict hyperdeformed states in Th, while also analyzing fission fragment angular distributions.
This paper investigates the far-from-equilibrium dynamics of a relativistic massive gas with various quantum statistics undergoing Bjorken expansion using the method of moments, revealing that the trace anomaly and bulk viscosity exhibit non-monotonic time evolution, depend sensitively on particle statistics and initial chemical potential, and converge to a universal late-time attractor regardless of initial non-equilibrium configurations.
This HYP2025 talk pays tribute to the late Tullio Bressani, Bogdan Povh, Toshimitsu Yamazaki, and Yoshinori Akaishi, honoring their enduring contributions to the development of strangeness nuclear physics.
This paper questions the compatibility of recent hypernuclear assignments from J-PARC E07 -capture emulsion events with those derived from other experiments.
This paper develops a non-hermitian Green's function theory for coupled-cluster methods by establishing a biorthogonal quantum framework, deriving diagrammatic expansions for the coupled-cluster self-energy and Bethe-Salpeter kernel, and introducing a new CC- approximation that bridges Green's function and coupled-cluster theories.
This paper investigates how decay channels influence near-threshold mass scaling using potential models, demonstrating that the pole of a quasibound state below the threshold is not continuously connected to that of a resonance state above the threshold, while clarifying the correspondence between single-channel complex and coupled-channel real potential approaches.
This paper extends the \textit{ab initio} Gamow Density Matrix Renormalization Group (G-DMRG) method to accurately describe broad nuclear many-body resonances by introducing novel truncation schemes and orbital ordering strategies based on entanglement, successfully demonstrating convergence and obtaining the first direct calculation of the \isotope[5]{H} ground state.
This study employs a transport approach to demonstrate that photon-tagged jets effectively mitigate selection bias, thereby revealing medium-induced angular broadening in PbPb collisions that contrasts with the narrowing observed in inclusive jets.
This paper investigates a second-order extension of perfect spin hydrodynamics in a boost-invariant expansion, finding that while spin dynamics feedback constrains polarization configurations, the resulting behavior remains nearly identical to the non-feedback case as long as the spin polarization magnitude stays below unity.
This paper presents a combined thermal and coalescence model for heavy-ion collisions in the few-GeV regime that successfully reproduces proton, pion, and deuteron yields but underpredicts the production of H and He nuclei by a factor of two compared to experimental data.
