This study demonstrates that interface engineering in a van der Waals heterostructure of the topological insulator BiTe and the antiferromagnet FePS induces spin-phonon coupling and modifies the magnetic ordering temperature, offering a pathway for controlling magneto-elastic modes in surface code spin logic devices.
This paper derives the general density and current correlation functions for layered metals to demonstrate that electromagnetic retardation effects, arising from anisotropy, mix longitudinal and transverse excitations to alter plasma mode dispersion and produce a distinctive double-peak structure in the density response observable via high-momentum spectroscopies.
This first-principles study reveals that linearly -dependent higher-order strain terms are crucial for accurately modeling the electronic structure of strained HgTe, explaining the camel-back feature in the tensile regime and supporting the emergence of a Weyl semimetal phase under compressive strain.
The study reveals that exchange interactions with a magnetic EuOx overlayer uncover a hidden, highly anisotropic uniaxial spin texture in the superconducting 2D electron gas at KTaO3 (110) interfaces, offering new avenues to explore the interplay between magnetism and 2D superconductivity.
This study characterizes the ferromagnetic kagome metal ScMn6(Sn0.78Ga0.22)6, revealing an in-plane easy magnetization axis that preserves a gapless Dirac cone and flat bands, thereby demonstrating how magnetic orientation modulates the material's topological electronic structure and anomalous Hall effect.
This paper demonstrates that an inversion-based approach using nonequilibrium Green's function formalism can accurately extract electron-photon coupling strengths from transmittance spectra in 1D disordered systems, achieving particularly high precision in the Aubry-André-Harper model due to its sharp metal-insulator transition.
This paper investigates charge and energy transport in monolayer graphene with smooth finite-range disorder by employing a nonperturbative approach that combines exact scattering matrices with the Boltzmann equation, revealing significant deviations from standard perturbative predictions and the Wiedemann-Franz law, particularly at low energies.
Using scanning tunneling microscopy and spectroscopy, this study reveals that marginally twisted monolayer-bilayer graphene reconstructs into a network of three distinct stacking domains with unique electronic textures and voltage-dependent tunneling hierarchies, including characteristic domain wall "twirling" around AAB nodes, thereby elucidating fundamental structure-property relationships in moiré-driven van der Waals heterostructures.
This study employs anharmonic non-equilibrium Green's function simulations combined with machine learning potentials to reveal that thermal conductivity in ultrathin silicon nanowires exhibits a nonmonotonic dependence on diameter due to hydrodynamic phonon flow at room temperature and quantized quasi-ballistic transport at cryogenic temperatures, overcoming the limitations of classical molecular dynamics in capturing quantum effects.
This paper argues that achieving ideal, domain-free negative capacitance in ferroelectric-dielectric heterostructures requires the domain wall energy parameter to exceed a critical threshold determined by the layer thicknesses, thereby stabilizing the system against domain formation.
