This paper investigates the Lee-Wick-Chern-Simons pseudo-quantum electrodynamics in 2+1 dimensions, demonstrating that the model is a gauge-invariant theory with massive excitations that naturally regulates ultraviolet divergences in one-loop quantum corrections while preserving unitarity and causality.
This study employs first-principles calculations to characterize the newly synthesized 2D Vivianene, revealing its room-temperature stability, indirect bandgap of 3.03 eV dominated by Fe d-orbitals, and enhanced optical absorption in the ultraviolet region, which collectively suggest its promising potential for optoelectronic and sensing applications.
This study utilizes DFTB simulations to reveal that manganese atoms preferentially intercalate into and embed within NbSe bilayers with a 0.68 eV diffusion barrier, exhibiting concentration-dependent inward migration that precedes clustering, thereby offering key insights into the stability and diffusion mechanisms of transition metal intercalation in 2D materials.
This first-principles study reveals that while pristine chalcogen vacancies in MoS and MoSe do not induce magnetism, the adsorption of azanide (NH) and ammonia (NH) on these defective monolayers generates localized magnetic moments, with MoSe exhibiting a notable 2.0 moment upon NH dissociation, thereby demonstrating a viable strategy for tuning magnetism in 2D materials for spintronic applications.
This study reveals that lead titanate (PbTiO3) exhibits distinct high-pressure behaviors depending on the synthesis path, remaining stable in a tetragonal phase up to 100 GPa under room temperature compression but dissociating into novel PbO and TiO2 polymorphs under laser-heated conditions, a phenomenon confirmed by combined synchrotron X-ray diffraction and density functional theory computations.
This paper investigates phonon-assisted tunneling in Jahn-Teller Ee impurity centers by incorporating both linear and quadratic vibrational interactions, revealing that phonon scattering broadens the energy spectrum and reduces resonance while identifying a specific range of quadratic interactions that preserves tunneling coherence at high temperatures, findings that align with ultrasonic attenuation measurements in doped AlO, GaAs:Mn, and GaAs:Cu crystals.
By combining high-resolution infrared spectroscopy and near-ambient-pressure scanning tunneling microscopy with theoretical calculations, this study elucidates the distinct CO adsorption behaviors on Rh/Fe3O4 single-atom catalysts, revealing how pressure conditions and CO-induced dimer dissociation govern the formation of monocarbonyl versus gem-dicarbonyl species.
This paper presents a generative model-driven framework combined with hierarchical thermodynamic and electronic screening to successfully identify 13 new thermodynamically stable electrides and 264 electron-rich compounds from thousands of chemical compositions, accelerating the discovery of materials with exceptional electronic properties.
This paper establishes a universal symmetry-based strategy for realizing topological altermagnets with magnonic quantum spin Hall effects and chiral magnon transport, demonstrating through first-principles calculations that bilayer VWS exhibits -wave altermagnetism with protected helical edge states and anisotropic thermal Hall responses, thereby opening new avenues for dissipationless magnonic devices.
This study demonstrates that van der Waals ferroelectric NbOI crystals exhibit highly efficient, anisotropic high-harmonic generation up to the 16th order at low intensities, driven by electron correlations from Peierls dimerization, thereby establishing them as promising materials for compact quantum light sources.
