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 motivates the use of quantum simulation to overcome the exponential computational scaling limitations of classical lattice field theory in studying dense matter and dynamical phenomena, while reviewing current theoretical, algorithmic, and hardware progress and outlining future challenges and opportunities.
This paper demonstrates that standalone relativistic hydrodynamic effective field theories are inherently acausal and necessitates the inclusion of transient ultraviolet modes to restore causality while preserving the correct late-time hydrodynamic behavior.
This paper proposes a first-principles framework using gradient flow and renormalization group transformations to analytically derive confinement in QCD, demonstrating that a scale-invariant gluon condensate drives the running coupling to an infrared fixed point consistent with infrared slavery.
Using the CoMBolt-ITA hybrid model to analyze recent LHC oxygen-oxygen collision data, the study concludes that collisions with centralities greater than 60% transition out of the fluid-like evolution regime, indicating a breakdown of hydrodynamic applicability as the system size approaches the mean free path.
This paper proposes that the thermodynamic Gibbs entropy of quark-gluon plasma is preserved during hadronization by being converted into the quantum entanglement entropy of confined partons within hadrons, a hypothesis supported by three independent estimates showing that a proton's internal entanglement entropy matches the magnitude of the QGP entropy from which it formed.
This paper compares perturbative and fully numerical approaches for modeling magnetized neutron stars with purely poloidal fields, finding that while the perturbative method (Konno-99) is accurate for observed magnetar fields but fails at extreme strengths ( G), the fully numerical LORENE code struggles with resolution issues at lower field strengths ( G).
This paper presents a unified open quantum system framework based on the Lindblad equation to describe both the suppression and thermal recombination of charmonium and bottomonium states in ultrarelativistic heavy-ion collisions undergoing Bjorken expansion.
This paper proposes a field-theoretical framework, analogous to the BEC-BCS crossover in ultracold atoms, to explain the hadron-quark crossover in dense matter by demonstrating that a tripling fluctuation effect naturally reproduces key quarkyonic features such as the speed of sound peak and baryon momentum-shell structure.
This paper establishes a self-consistent spectral framework that unifies the Ichimura-Austern-Vincent inclusive non-elastic breakup theory with the Trojan Horse Method by demonstrating that the latter's resonance-strength formula is a specific non-perturbative reduction of the former's per-pole distorted-wave Born approximation cross sections under well-defined sub-Coulomb conditions.
This study compares the longitudinal deposition of conserved quantities in initial-state models based on string dynamics (SMASH) and saturation (McDipper) across a wide range of collision energies, revealing that while the models agree at lower energies, they exhibit substantial differences in energy and baryon deposition at higher center-of-mass energies.
