This study investigates the impact of magnetic (Fe) and non-magnetic (Zn) impurities on the tetragonal crystal structure and paramagnetic properties of overdoped electron-doped Eu2-xCexCuO4 superconductors, revealing that impurity substitution enhances localized magnetic contributions as Ce concentration increases.
This paper demonstrates that while valley domain walls in symmetry-broken rhombohedral graphene act as impenetrable barriers to metallic transport, intervalley interactions are essential for enabling both electron transmission across these walls and the flow of supercurrents in chiral superconducting Josephson junctions.
This paper establishes a robust quantum privacy framework based on Pauli–Weyl randomization that minimizes pairwise - Rényi divergences under utility constraints, providing exact analytical solutions for binary qubit and diagonal qudit ensembles while proving stability and optimality conditions for practical quantum information protection.
This paper proposes and numerically validates a novel Kretschmann-configured Long-Range Surface Plasmon Resonance (LRSPR) sensor utilizing the anisotropic properties of ReS₂, a silver plasmonic layer, and a lithium niobate passivation layer to achieve ultra-high imaging sensitivity and detection accuracy for advanced biomolecular sensing.
This study demonstrates that depositing ZnO thin films via a spray pneumatic technique at 450°C yields optimal structural, optical, and electrical properties, including a maximum crystallite size of 15.19 nm, approximately 85% transparency, a band gap of 3.31 eV, and the lowest electrical resistivity of 0.064 Ω·cm.
This study demonstrates that applying an electric field to MoSe₂/WSe₂ van der Waals heterostructures induces a pronounced valley-selective Quantum Confined Stark Effect, where strong spin-orbit coupling and spin-valley locking create significant asymmetry in exciton energy shifts and lifetimes between the K and K′ valleys, particularly at small twist angles, thereby enabling the design of electrically tunable, valley-selective photonic devices.
This paper demonstrates a room-temperature, single-pixel computational short-wave infrared imaging system at 1550 nm using hyperdoped silicon photodetectors with ultrafast laser processing, achieving high detectivity and enabling low-cost, monolithically integrated multispectral sensors without cryogenic cooling.
This study utilizes DFT calculations to demonstrate that double perovskite hydrides X2PdH6 (where X = Li, Na, K, Rb) exhibit promising hydrogen storage capacities and desorption temperatures within the ideal range for Li and Na variants, alongside stable mechanical properties and optoelectronic potential suitable for clean energy applications.
This study develops a novel spatiotemporal nonlocal elasticity model incorporating strain gradient effects and temperature-dependent thermal conductivity to accurately analyze the thermal vibrations of rotating nanobeams under laser irradiation, revealing that temporal memory and centrifugal stiffening significantly influence deflection and temperature distribution for improved design of nanoscale thermomechanical systems.
This paper evaluates the robustness of Rayleigh-Marchenko redatuming for generating multiple-free seismic images and angle gathers from band-limited data and smooth velocity models, demonstrating its effectiveness in handling mode-converted waves in elastic media and its particular suitability for ocean-bottom and borehole seismic applications despite its underlying acoustic assumptions.
