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.
Using generalized hydrodynamics, this study reveals that thermal beating in the dipole-compression modes of a harmonically trapped 1D Bose gas arises from the distinct thermal populations of particle and hole excitations, which generate two evolving oscillation frequencies that deviate from classical hydrodynamic predictions across the interaction crossover.
This paper demonstrates that physics-informed neural networks (PINNs) can significantly enhance the efficiency, speed, and energy consumption of nuclear coherent population transfer in open three-level systems by automatically learning optimal laser pulse sequences, thereby overcoming lifetime limitations in applications like nuclear clocks and batteries.
This paper presents a deterministic quantum algorithm that efficiently constructs antisymmetric fermionic states in first quantization mapping using -gates and dirty ancilla qubits, offering a significant performance advantage over sorting-based methods for systems where the particle count is less than the square root of the available orbitals.
This study demonstrates that while the -process path approaches the neutron-drip line under low-temperature and high-neutron-density conditions, variations in the nuclear masses of exotic nuclei in the and region significantly alter superheavy and specific mass-region abundances (, $175-185$, $200-205$) without substantially affecting the characteristic -process peaks at , $195$, and the rare-earth peak.
This paper utilizes chiral kinetic theory to demonstrate that the chiral anomaly induces a novel dynamical screening mechanism and a gapped collective mode in relativistic massless fermion plasmas under strong magnetic fields, with significant implications for neutron star phenomenology.
This paper presents an analytic probabilistic description of ultra-high-energy cosmic ray interactions, modeling them as Markov jump processes to overcome the limitations of current deterministic and Monte Carlo approaches in accurately characterizing nuclear cascades and their impact on observed cosmic ray composition and spectrum.
This paper introduces the first public GPU-accelerated framework for X-ray pulse profile modeling that achieves high-fidelity accuracy with massive speedups (2–5 ms per evaluation), thereby resolving the accuracy-speed bottleneck in Bayesian inference and enabling the exploration of previously intractable hotspot geometries and equation-of-state constraints.
Using chiral perturbation theory, this study derives the one-pion exchange potential in strong magnetic fields, revealing that the potential's range decreases in all directions and induces a deuteron energy shift comparable to its binding energy at field strengths around the pion-mass scale.
Using a complex-energy approach and direct time propagation, this study investigates the ill-defined radius of proton resonances, revealing an early-time plateau where the Gamow resonance radius matches experimental values and demonstrating a nonmonotonic dependence on decay energy that includes a halolike charge radius enhancement across the threshold.
This study utilizes PYTHIA8 simulations to investigate the correlation between prompt and nonprompt production and transverse spherocity in 13 TeV $pp$ collisions, demonstrating how this event-shape observable can distinguish hard QCD processes from underlying events influenced by multiple parton interactions.
