This paper generalizes the jet transport coefficient to a Lorentz-covariant diffusion tensor to describe momentum broadening in out-of-equilibrium media, revealing new energy-momentum correlations and demonstrating that non-equilibrium corrections can either enhance or reduce broadening depending on the initial distribution.
This paper demonstrates that shock-induced density and temperature perturbations in core-collapse supernovae and neutron star mergers can overcome electron mass damping to sustain the chiral plasma instability and generate substantial ohmic heating via the chiral magnetic effect.
This theoretical study predicts the existence of well-isolated, deeply bound atoms with narrow widths and demonstrates that reactions on light nuclei are a highly effective method for observing these states as discrete peaks, thereby offering new insights into -nucleus interactions.
This paper investigates how magnetic fields in heavy ion collisions induce quarkonia spin alignment through both orbital wave function distortion and spin state mixing, finding that the spin contribution dominates phenomenologically while the subleading orbital effect offers a unique probe for studying quarkonium structural changes.
This study utilizes the AMPT model to demonstrate that the elliptic flow of charged hadrons in 200 GeV d+Au collisions is primarily driven by early-stage partonic interactions rather than hadronic rescattering, successfully reproducing experimental trends and highlighting the significance of parton scattering mechanisms in asymmetric collision systems.
This paper presents a scale setting and strong coupling determination for 2+1 flavor lattice QCD using HISQ ensembles, reporting precise gradient flow scales ( and ) and a potential scale () while providing a polynomial ansatz for predicting lattice spacings and estimating .
This paper proposes and validates a Pearson correlation between spectator and charged-particle forward-backward asymmetries as a robust, data-driven observable to constrain models of preferential emission and spectator breakup dynamics in heavy-ion collisions.
This paper introduces a novel virtual rishon framework that enforces gauge symmetry via intermediate quantum-link representations to enable scalable simulations of lattice gauge theories in d+1 dimensions using both classical tensor networks and near-term quantum hardware, validated by benchmarking on the multi-flavor Schwinger model and 2D string tension.
This chapter reviews the similarity renormalization group method for nuclear forces, detailing its flow equations, diagonalization mechanism, and induced many-body interactions to highlight its role in advancing first-principles nuclear calculations.
This paper analyzes nuclear matter properties and neutron star structures using an extended linear sigma model, demonstrating that the introduction of the meson creates a plateau in symmetry energy consistent with experimental constraints, while a negative pion-nucleon sigma term is required to achieve a stiff equation of state capable of supporting massive neutron stars.
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.
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.
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 ratio below 1.41, thereby defining the limits of this decay mode's existence.
This paper introduces a novel, size-extensive, and convergent degenerate coupled-cluster (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.
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.
This study assesses the implementation of radiation protection systems in four Ethiopian hospitals, revealing that while background and idle radiation levels are safe, poor operational practices and a lack of monitoring equipment lead to dangerously high exposure for staff during active X-ray procedures, necessitating immediate training, modern equipment, and dedicated radiation protection oversight.
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.
This paper develops a quantum kinetic theory for Quantum Chromodynamics that incorporates leading-order collision terms to reproduce the Boltzmann equation at lowest order and predict spin polarization of quarks and gluons at next order, revealing distinct behaviors for vortical versus non-vortical gradients and a mechanism for spin-orbital angular momentum conversion via inelastic collisions.
This paper employs SU(2) chiral perturbation theory with isospin-breaking effects to derive the QCD -vacuum solution and compute the temperature dependence of topological observables and domain wall tension up to next-to-leading order, revealing distinct monotonic behaviors for different cumulants and providing crucial theoretical insights for axion physics in hot QCD matter.
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.
