nucl-th papers | Gist.Science

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.

Static Fission Properties of Even-Even Actinides within the Warsaw Macroscopic-Microscopic Model Using Fourier-over-Spheroid Parameterization

This paper presents a systematic study of fission barriers and static properties for even-even actinides from Th to Cf using the Warsaw macroscopic-microscopic model with a high-resolution Fourier-over-Spheroid parameterization, revealing good agreement with empirical data and identifying a distinct third hyperdeformed minimum in Thorium isotopes that is absent in heavier actinides.

Trigonometric continuous-variable gates and hybrid quantum simulations of the sine-Gordon model

This paper introduces a new universality paradigm for hybrid qubit-qumode quantum computing based on trigonometric continuous-variable gates, demonstrating their effectiveness through a deterministic ancilla-based implementation and a successful simulation of the lattice sine-Gordon model, including ground state preparation, real-time dynamics, and kink profile extraction.

Degenerate coupled-cluster theory

This paper introduces a novel, size-extensive, and convergent degenerate coupled-cluster ( $\Delta$ CC) theory capable of handling arbitrary reference states and a related quasidegenerate variant (QCC) for strong correlation, demonstrating superior accuracy and convergence over existing methods like EOM-CC, CI, and MBGF through high-order implementations.

Evidence for Multimodal Superfluidity of Neutrons

This paper presents theoretical and experimental evidence for a new phase of matter called multimodal superfluidity in neutron-rich systems, characterized by the coexistence of s-wave pairs, p-wave entangled double pairs, and quartets, which is predicted to occur in various fermionic systems and has significant implications for the structure and dynamics of neutron star crusts.

Radius-Flow Entanglement in Hadron States and Gravitational Form Factors

This paper proposes a lattice-ready entanglement observable, the vacuum-subtracted radius flow of Rényi entropy, to extract hadronic gravitational form factors by fitting flow data to a basis of spin-0 and spin-2 templates, thereby enabling the discrimination of scalar versus spin-2 entanglement control through the location and characteristics of the flow's extremum.

Microscopic description of cluster radioactivity fission valleys along isotopic and isotonic chains

This paper utilizes the microscopic Gogny Hartree-Fock-Bogoliubov approximation to demonstrate that while a cluster radioactivity fission valley exists across a wide range of isotopic and isotonic chains, it diminishes and disappears in neutron-deficient nuclei with an $N/Z$ ratio below 1.41, thereby defining the limits of this decay mode's existence.

Empirical Universal Scaling of Neutron-Skin Curvature Across the Nuclear Chart

This paper demonstrates that an empirical, dimensionless "neutron-skin curvature" derived from experimental charge radii collapses data from over 800 nuclei across 88 elements onto a single universal curve when plotted against normalized neutron excess, revealing a robust geometric scaling law that accounts for 88% of the variance without requiring element-specific tuning or interaction models.

Understanding the Structure of Doubly-Heavy Tetraquarks based on the Diquark Model

By applying the Gaussian Expansion Method to the Silvestre-Brac potential within a diquark model, this study reveals that centrifugal forces acting on light degrees of freedom invert the expected mass hierarchy in doubly-heavy tetraquarks, a robust mechanism confirmed across various heavy-hadron systems.

Lattice extraction of the Collins-Soper kernel using the auxiliary field representation of the Wilson line

This paper presents a preliminary lattice extraction of the Collins-Soper kernel in Collins' scheme using an auxiliary fermion field representation of the Wilson line, comparing the "ratio" and "double ratio" methods to achieve high statistical precision.

From Orthogonalizing Pseudopotential to the Feshbach-Schur Projection

This paper demonstrates that the Orthogonalizing Pseudopotential (OPP) method is equivalent to the singular limit of the Feshbach-Schur projection, providing a closed operator-level identity via the Schur complement that eliminates Pauli-forbidden states algebraically without relying on large auxiliary parameters.
