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?

This paper reviews the application of the ab initio no-core shell model with continuum (NCSMC) approach, utilizing chiral nuclear forces to unify the description of bound and unbound states in light halo nuclei such as He, B, Be, and C, while also addressing challenges in modeling Borromean systems and presenting preliminary studies on Be and Li.
This paper reviews the role of spin, magnetic fields, and nucleonic superfluidity in the interior physics of compact stars, utilizing a meta-modeling framework to connect microscopic interactions with macroscopic observables while addressing unresolved dynamics such as vortex lattices, pulsar glitches, and potential quark deconfinement.
This paper revises the Rhoades-Ruffini bound by relaxing assumptions about the onset of stiff non-nucleonic matter, demonstrating that the theoretical maximum mass of neutron stars could reach or higher and providing a fit formula for this limit based on the speed of sound and transition density.
This paper proposes and validates a method to compute complete probability distributions for fission observables, such as total kinetic energy, by sampling nucleonic configurations from a Bogoliubov vacuum projected onto good particle number, revealing that significant fluctuations in actinide scission are already captured within the mean-field framework.
This paper extends the Koopman-von Neumann-Sudarshan Hilbert space formulation to relativistic QCD, demonstrating that the covariant Wigner operator is fundamentally a quantum probability amplitude projected onto phase space, thereby offering a unified framework that clarifies the origin of nonclassical features like negativity and establishes a transparent foundation for parton distribution functions.
This paper highlights that recent experimental challenges in describing isomeric cross sections for Tc isotopes reveal significant limitations in current nuclear level density models when using standard rigid-body moment of inertia values, thereby underscoring the urgent need for direct measurements of average resonance spacings to validate and improve angular-momentum dependence assessments.
The STAR experiment at RHIC presents high-statistics femtoscopy results from Isobar and Au+Au collisions, revealing an attractive interaction in - pairs and a bound state in - pairs through the analysis of final-state correlations.
Inspired by McGlynn and Simenel's work, this study demonstrates that the time-dependent generator coordinate method (TDGCM), utilizing real-time mean-field states as generators, successfully overcomes the spurious self-trapping effect in interacting two-particle tunneling to reproduce exact quantum dynamics while providing critical insights into collective versus single-particle behaviors.
This paper proposes a formal framework utilizing Takagi factorization of the Jost-RPA S-matrix residue to define intrinsic collectivity in continuum resonance states, introducing new indices that reveal hidden collective modes in O which are decoupled from their observable line shapes.
This study utilizes a two-flavor Nambu--Jona-Lasinio model within a kinetic theory framework to demonstrate that finite rotation modifies the transport properties of quark matter by reducing the chiral condensate, inducing anisotropy in shear viscosity and electrical conductivity, and generating significant non-dissipative Hall-like currents at zero net density.
