This paper identifies a unique dielectric multicritical point in relativistic degenerate quantum plasmas where the matching of Coulomb and relativistic degeneracy energy scales causes the collapse of screening poles and a transition from quadratic to quartic spatial dispersion, fundamentally altering the screening mechanism at densities near the onset of relativistic degeneracy.
This paper proposes and numerically demonstrates a novel GeO₂-doped all-solid anti-resonant fiber with a rod-assisted structure that achieves large mode areas, ultra-low loss, and robust single-mode operation for efficient high-power laser beam delivery at 1.064 μm.
This paper demonstrates that a large-volume scenario-based multi-axion ensemble successfully resolves the parametric obstruction preventing single-axion models from simultaneously accommodating ultralight dark energy and visible-sector axion-like particles, yielding a reproducible map of 35,123 correlated phenomenological islands where distinct canonical eigenvectors decouple dark-energy dynamics from visible ALP phenomenology.
This paper presents a versatile, compact GHz phononic adapter that seamlessly bridges unpatterned continua and topological phononic crystals, enabling near-unity transmission, valley flipping, and frequency-tunable directional steering of acoustic waves for advanced integrated phononic circuits.
This study benchmarks the IBM \texttt{ibm\_marrakesh} quantum hardware by simulating a 15-qubit tilted-field Ising model, revealing that while the device captures early-time magnetization trends, noise and decoherence significantly degrade long-range correlation spreading and local magnetization fidelity compared to ideal simulations.
This study investigates the uniaxial fatigue mechanical properties of double-fissured red sandstone under freeze-thaw cycles through experimental testing and the development of an improved variable-order fractional constitutive model, revealing that freeze-thaw damage accelerates macroscopic deterioration, reduces stress thresholds, and promotes shear failure.
This study employs an inverse method on eddy-resolving zonal barotropic channel simulations to determine how the coefficient of potential vorticity diffusivity depends on wind stress and topographic roughness within the eddy saturation regime.
This study characterizes the turbulent velocity fields and aerosol cloud dynamics generated by human coughing and sneezing through experiments with 50 volunteers, revealing that while near-field transport is dominated by high-velocity jets, aerosol dispersion at larger distances becomes increasingly dependent on ambient airflow conditions.
This paper proposes a measurement-device-independent quantum secure direct communication protocol that leverages polarization-spatial hyperentanglement and an active three-intensity decoy-state mechanism to securely transmit messages by mitigating multiphoton risks and eliminating detector-side vulnerabilities in practical scenarios.
This paper investigates the physical mechanisms and modelling requirements for accurately simulating the onset and evolution of immiscible viscous fingering in porous media at high viscosity ratios, demonstrating that matching experimental finger scales and saturation patterns necessitates a multi-step approach involving linear stability analysis, the selection of a sufficiently small initial unstable wavelength to account for nonlinear merging, the inclusion of small-scale channelling effects, and a weakly oil-wet capillary pressure function.
