By combining advanced photoemission and absorption spectroscopy with cluster model calculations, this study quantifies the electronic parameters of NiTe to reveal that a negative charge-transfer energy and finite on-site Coulomb repulsion drive its classification as a moderately correlated type-II Dirac semimetal, distinguishing it from strongly correlated insulators like NiO.
This study resolves the absence of expected correlation-induced band narrowing in the topological metal CoTe by demonstrating that a negative charge-transfer energy and reduced on-site Coulomb interaction, validated through spectroscopic measurements and cluster model simulations, fundamentally shape its unique electronic structure and enable its topological behavior.
This study combines density functional theory and machine learning potentials to investigate hydrogen diffusion in TiCr Laves phases, revealing that migration barriers depend on bond-breaking requirements, diffusion exhibits non-monotonic concentration dependence, and experimental discrepancies are likely caused by defect-induced hydrogen trapping.
Researchers successfully synthesized the bulk quantum magnet M-YbTaO4, featuring a geometrically frustrated stretched diamond lattice of spin-1/2 Yb3+ ions that exhibits no long-range magnetic ordering down to 1.8 K, by utilizing high-pressure conditions to stabilize this phase and its entire YbNbxTa1-xO4 solid solution, which are inaccessible via ambient-pressure methods.
This paper reports the first experimental demonstration of a frequency- and time-resolved single-molecule fluorescence quantum light spectroscopy (SMFg2-QLS) on IDTBT polymer chains, successfully measuring second-order quantum coherence functions that reveal non-trivial excited state dynamics and suggest the presence of intrinsic quantum coherence.
By employing time-resolved optical techniques to reshape the free-energy landscape of SnTe, this study reveals a non-adiabatic decoupling between nonlinear polarization dynamics and harmonic lattice motion, providing a unified framework for understanding the mixed displacive and order-disorder nature of ferroelectric soft modes.
This paper introduces MAESTRO, a multi-agent large language model framework that autonomously iterates through reasoning, proposal, and reflection to discover high-performance single atom catalysts for the oxygen reduction reaction, successfully identifying novel design principles that break conventional scaling relations.
By engineering the interfacial exchange coupling between ferromagnetic SrRuO₃ and LaCoO₃, this study demonstrates the induction of noncollinear spin stripes and magneto-transport anisotropy while suppressing skyrmion formation, highlighting the potential of interfacial design to control spin textures in topological-like ruthenate superlattices.
Using first-principles simulations, this study investigates the structural, mechanical, and electronic properties of various halide perovskite monolayers, revealing the thermodynamic and mechanical instability of the ABX4 stoichiometry, strong mechanical anisotropy driven by Pb–X covalent bonding, and electronic characteristics similar to 3D counterparts but with larger band gaps and spin splitting in non-symmetric phases.
This study reveals that despite cation off-centering and disorder, AgBiS2 exhibits intrinsic band-like transport due to its close-packed structure, suggesting that carrier localization in nanocrystal films is driven by extrinsic factors rather than inherent material properties.
