This study computationally validates the tight-binding approximation as a reliable framework for modeling graphene's electronic band structure, successfully reproducing its semimetallic nature, zero band gap, and massless Dirac fermion behavior with a Fermi velocity of approximately 1.0 × 10⁶ m/s using a hopping parameter of 2.8 eV.
This study utilizes atomic force microscopy and nanoindentation to characterize the microscopic mechanical heterogeneity and damage evolution of coal, revealing distinct differences between powder and block samples and establishing a theoretical link between their mechanical responses based on Hertz contact theory to support deep mining safety.
This study demonstrates that hexagonal boron nitride cavities serve as a versatile platform for investigating quantum chaos in phonon-polaritons by experimentally observing signatures like quantum scarring and Wigner-Dyson level statistics in chaotic geometries, which are successfully reproduced by a theoretical framework incorporating angle-dependent boundary reflections.
This study utilizes two-dimensional particle-in-cell simulations to demonstrate that self-generated magnetic dipole vortices in the upstream region of relativistic collisionless shocks serve as an efficient pre-acceleration mechanism for ions by maintaining phase matching and extending interaction time, thereby providing the energetic seed particles necessary for subsequent shock acceleration.
This study demonstrates that the Virtual Crystal Approximation with norm-conserving pseudopotentials (VCA-NC) is a computationally efficient and accurate alternative to conventional supercell models for predicting the phase stability of metastable Ti-Nb biomedical alloys, successfully identifying critical niobium composition thresholds that align with experimental findings.
This paper demonstrates a scalable inertial-sensing modality using a self-sustained mechanical frequency comb generated via three-wave-mixing parametric excitation in a PZT-on-silicon bridge, which overcomes the traditional Q–bandwidth trade-off of single-mode MEMS accelerometers by enabling simultaneous, multi-channel acceleration detection across multiple comb lines.
This paper demonstrates a monolithically integrated mirror–phaseshifter–emitter system in a GaAs waveguide that utilizes a nano-opto-electro-mechanical phase shifter to actively control the optical phase between a quantum dot and its mirror image, thereby enabling real-time modulation of the local density of optical states and the emitter's radiative decay rate for programmable quantum photonic networks.
This paper describes the BEF-2026 apparatus, which utilizes a near-light-speed energy sheath to synthesize high-yield CVD diamond while simultaneously employing the growth rate differential between internal and external substrates as a "chemical clock" to test the hypothetical Börekci metric against predictions from general relativity.
This paper utilizes the rigorous coupled-wave analysis method to demonstrate that a multilayer periodic silver grating with slit arrays significantly enhances extraordinary optical transmission through surface plasmon resonance coupling at the metal–dielectric interfaces and between adjacent layers.
This study characterizes gas-filled capillary discharge targets and utilizes particle-in-cell simulations to demonstrate how optimized plasma channels can enhance the stability and quality of electron beams for high-repetition-rate laser-plasma accelerators aimed at compact free-electron laser applications.
