This study demonstrates that epitaxial, L21-ordered Co2MnSi waveguides with robust structural integrity and intrinsic magnetocrystalline anisotropy enable bias-field-free nonlinear half-metal magnonics by reshaping spin-wave dispersion to suppress instabilities and stabilize low-field operation.
This paper proposes an effective statistical field theory where classical spacetime geometry and gravitational dynamics emerge from the coarse-grained curvature statistics of a confining non-Abelian gauge connection on a dynamical graph, utilizing mechanisms like gauge-to-metric reconstruction and double-copy squaring to derive the metric and graviton while demonstrating through renormalization-group analysis and numerical tests that this framework reproduces Einstein-Hilbert gravity, black hole entropy, and a confinement-deconfinement phase transition.
This paper experimentally demonstrates that sustained entirely detached growth of antimony-based semiconductor crystals can be achieved under terrestrial gravity in a vertical directional solidification configuration using conical-bottom quartz ampoules, which stabilize the crystal-ampoule gap and improve crystallization quality by suppressing wall-induced defects.
By combining off-axis electron holography with orbital-free density functional theory, this study quantitatively reveals that work-function differences drive charge redistribution not only at individual metal–metal heterojunctions but also across their external surfaces, thereby providing a new framework for probing local contact potentials and understanding metal–support interactions at the single-particle resolution.
This study demonstrates that symmetry-guided interfacial Ti incorporation in epitaxial Sr-doped HfO₂ stabilizes the ferroelectric phase and regulates carrier transport, enabling highly durable memristors with 1,104 analog states that achieve ultra-low-energy in-memory computing for tasks like image reconstruction and robotic control.
This paper presents the first realization of high-sensitivity quantum-enhanced tensor magnetometry using a bright, multidimensional polarization-entangled light source with three squeezed Stokes operators, achieving a 6 dB quantum enhancement in measuring magnetic field gradient direction and amplitude.
This study presents a thermally and angularly stable broadband thermal emitter based on a Ni-nanowire metasurface that achieves approximately 94.23% average emissivity across 200–5000 nm and a photothermal conversion efficiency of 94.3% at 400K, making it highly effective for thermophotovoltaics and infrared sensing applications.
This study demonstrates that optimizing Tm₂O₃ doping at 0.50 mol% significantly enhances the electrical performance of ZnO-Cr₂O₃-based varistors by refining grain size and increasing grain boundary barrier height, resulting in a high voltage gradient, superior nonlinear coefficient, and low leakage current.
This study demonstrates that force-based rolling resistance measurements are highly sensitive to geometric misalignments and validates a theoretical model capable of accurately predicting and correcting these alignment-induced errors across both flat and cylindrical testing surfaces.
This study utilizes time-resolved photoluminescence and pump-probe techniques to investigate the ultrafast dynamics of Bi2TexSe3-x nanosheets, revealing that increasing selenium content induces a dominant mechanism reversal from carrier recombination to thermal effects, evidenced by shifting PL lifetimes and accelerated electron-phonon relaxation.
