Charge-Transfer Electronic Structure of NiX2_2 (X = S, Se)

Using DFT+DMFT with optimized double-counting corrections to match experimental spectra, this study reveals that NiS2_2 and NiSe2_2 possess a smaller charge-transfer energy than previously thought, leading to significant ligand-to-Ni charge transfer, reduced Ni local moments, and a clarified evolution of low-energy electronic structures across the NiS2−x_{2-x}Sex_x series driven by the interplay between Ni upper Hubbard bands and antibonding chalcogen-dimer states.

The Locality Cost of Fully Flat Hopf Insulators

This paper proves that while Hopf topology allows for a single exactly flat band with strictly finite-range hopping, achieving a fully flat two-band spectrum in a gapped, Hermitian system necessarily requires sacrificing strict locality or the energy gap, forcing the non-trivial topology to manifest as either partner-band dispersion or exponentially decaying, infinitely supported hopping tails.

Linker Functionalization and pH Tuning Enhance Solar-Driven Catalytic CO2_2 Reduction in MOF-5

This study demonstrates that combining linker functionalization (particularly with COOH groups) and pH tuning effectively narrows MOF-5's band gap into the visible range while optimizing reduction energetics, with Sr- and Ba-based nodes offering the most favorable conditions for efficient solar-driven CO2_2 reduction.

Vitrification-Devitrification Enables Tunable Photonic and Gas Sorption Properties of Zeolitic Imidazolate Frameworks

This study demonstrates that CO₂ sorption analysis and controlled annealing can quantify the microporosity of ZIF glasses and reveal a tunable relationship between their structural porosity and photonic properties, enabling the rational design of multifunctional MOF glasses.

Molecular-dynamics-based modal analysis of heat transport in quasi-one-dimensional systems from a symmetry-adapted perspective

This paper proposes a symmetry-adapted modal analysis method using line-group projection operators to overcome scalability and degeneracy issues in conventional approaches, demonstrating its effectiveness in identifying unique conduction channels and quantifying cross-channel correlations in quasi-one-dimensional systems like double-walled nanotubes.

Direct Observation of the Zigzag Edge States of a Supramolecular Diatomic Kagome Lattice

Researchers successfully fabricated a supramolecular diatomic Kagome lattice using a triptycene derivative on a Pb(111) surface and provided direct experimental evidence, supported by calculations, of its topological zigzag edge states governed by Zak phase quantization.

From Goldene to Noblene: exhaustive enumeration of the ordered Au-Ag-Cu monolayer alloys

This study combines exhaustive enumeration and density functional theory to map ordered Au-Ag-Cu monolayer alloys, revealing that atomic arrangement rather than composition dictates mixing energy and identifying a dynamically stable, metallic equimolar structure named "Noblene" that exhibits exceptional mechanical properties and a plausible synthesis route via Goldene.
