Modeling phase separation in polymer-derived carbonitride ceramics through extended machine learning molecular dynamics

This study employs a machine learning interatomic potential trained on over 9,000 configurations to simulate large-scale molecular dynamics of silicon carbonitride systems, revealing that thermal treatment drives phase separation where defective carbon rings mediate the nucleation of graphene-like sheets within the amorphous matrix, thereby explaining the material's unique hybrid properties.

Tuning the low-energy band structure in twisted bilayer WSe2

Using nano-ARPES, researchers demonstrate that while the momentum positioning of valence band maxima in twisted bilayer WSe2 remains fixed, the twist angle can be used to tune the energetic separation between hole bands at the K and Γ points by over 100 meV, offering a pathway to control band gaps and spin-dependent electron-phonon coupling in 2D devices.

Spin Peltier effect in graphene

This paper theoretically demonstrates that an external magnetic field enhances the spin-Peltier effect in graphene/ferromagnetic insulator heterostructures by quantizing the electronic spectrum into Landau levels, where level crossings significantly amplify spin-flip scattering and the resulting temperature difference, offering a sensitive probe for discrete energy levels in such hybrid systems.

Shear-Mode Raman Imaging of Ferroelectric Switching in Multilayer 3RR-MoS2_2

This study employs shear-mode Raman imaging and second-harmonic generation to reveal that ferroelectric switching in multilayer 3RR-MoS2_2 is a non-uniform, domain-wall-mediated process governed by pinning sites and exfoliation-created boundaries, which facilitate partial stacking transformations and distinct chiral orientations.

Ultra-Confinement of Polaritons in Single Atomic Layer Ag Photonic Quantum Dots

This paper presents a novel analytical approach using scattering-type scanning near-field optical microscopy to overcome previous limitations in quantitative analysis, successfully mapping the local propagation constant of polaritons in SiC/2D-Ag/EG photonic nanostructures and demonstrating their ultra-confinement in both vertical (∼λ\sim\lambda/50) and lateral (∼λ\sim\lambda/40) directions by a single atomic layer of silver.

Huge ultrafast spin Seebeck effect mediated by laser-excited superdiffusive magnon currents

This paper introduces an ab initio-parameterized microscopic framework based on the quantum Boltzmann equation to reveal a superdiffusive transport regime and a huge ultrafast spin Seebeck effect in laser-excited bcc Fe films, overcoming the limitations of traditional diffusive models in describing nonthermal magnon dynamics.
