Higher-order topological insulators in two-dimensional antiferromagnetic and altermagnetic chromium-based group-IV chalcogenides

Based on first-principles calculations and theoretical analysis, this study identifies a family of monolayer chromium-based group-IV chalcogenides as a new class of two-dimensional magnetic higher-order topological insulators that host robust, quantized corner states protected by lattice symmetry in both antiferromagnetic and altermagnetic ground states.

Grain Growth Kinetics in (Cr,Mo,Ta,V,W)C1-{\delta} High-Entropy Carbide Ceramics

This study investigates the grain growth kinetics and densification behavior of single-phase (Cr,Mo,Ta,V,W)C1-{\delta} high-entropy carbide ceramics during spark plasma sintering, revealing that elevated temperatures promote chemical homogenization and grain coarsening with an apparent activation energy of approximately 620 kJ mol-1, consistent with diffusion-controlled mechanisms.

Tantalum-Encapsulated Niobium Superconducting Resonators: High Internal Quality Factor and Improved Temporal Stability via Surface Passivation

This paper demonstrates that capping niobium superconducting resonators with a thin tantalum layer significantly enhances their internal quality factor and temporal stability by suppressing the formation of lossy niobium oxide and replacing it with a more stable tantalum-based interface.
