Using reactive molecular dynamics simulations with the Tersoff force field, this study reveals that Me-graphene monolayers and nanotubes exhibit Young's moduli ranging from approximately 414 to 483 GPa and undergo brittle fracture directly from the elastic regime without plastic deformation.
This paper theoretically demonstrates that interfacial Dzyaloshinskii-Moriya interaction in nonmagnetic/noncollinear-antiferromagnetic bilayers with stacked-Kagome structures can manifest as a uniaxial magnetic anisotropy for the antiferromagnetic order parameter when the Kagome planes are perpendicular to the film surface, thereby revealing a novel microscopic mechanism for magnetic anisotropy in such systems.
This paper demonstrates that uniaxial periodic strain in monolayer graphene creates a quasi-one-dimensional moiré lattice with flat bands, where electron-electron interactions induce Fermi-level pinning, Kohn-Luttinger-like pairing instabilities, and unconventional superconductivity enhanced by interband effects and metastable charge textures.
This paper demonstrates that extrinsic anomalous Hall conductivity can be comparable to or even essential for the intrinsic contribution in altermagnets, particularly in those with finite Dzyaloshinskii-Moriya interactions or large exchange splitting, due to the nonanalytic dependence of the intrinsic effect on spin-orbit coupling arising from lifted spin degeneracy.
This paper demonstrates that pure dephasing, rather than static disorder, is sufficient to induce integer quantum Hall criticality in quantum anomalous Hall systems by generating a topological nonlinear sigma model with instanton-driven flow, a prediction confirmed by simulations of the Qi-Wu-Zhang model.
This paper presents a scalable method for producing near cm-sized, single-crystalline monolayer graphene free of multilayer domains by leveraging a specific surface reconstruction of 4H-SiC(0001) to enable one-step delamination, a breakthrough confirmed by the observation of the half-integer quantum Hall effect and demonstrated on 4-inch wafers.
This paper investigates how nonlinear self-action in resonant dielectric metasurfaces supporting quasi-bound states in the continuum manifests through distinct intensity-dependent signatures—deviations from cubic scaling under picosecond excitation versus spectral reshaping under femtosecond excitation—depending on the temporal coupling between the pump pulse and the resonant mode.
This paper proposes a microscopic fermionic open quantum system coupled to Markovian reservoirs that emulates black-hole physics through an effective non-Hermitian geometry, demonstrating how steady-state currents and frequency-resolved correlations reveal analogue Hawking radiation signatures and fermionic partner amplitudes.
This paper presents a first-principles framework combining density-functional theory, Wannier functions, and charge center evolution to accurately determine the critical electric fields for topological phase transitions in silicene, germanene, and stanene, yielding significantly improved predictions over previous tight-binding models by fully accounting for screened electronic structures and dielectric responses.
This paper demonstrates that chemically derived multilayer graphene films with thickness and carrier density fluctuations exhibit a large Nernst effect at millitesla magnetic fields, achieving transverse thermopower values up to 250 V/K and highlighting their potential for scalable thermoelectric energy generation.
