On the bounds of the forgotten topological index
TURKISH JOURNAL OF MATHEMATICS, 2017 Summary: The forgotten topological index is defined as the sum of cubes of the degrees of the vertices of the molecular graph \(G\). In this paper, we obtain, analyze, and compare various lower bounds for the forgotten topological index involving the number of vertices, edges, and maximum and minimum vertex degree.

Unexpected Asymmetric Mn‐Sb Site Mixing and Reentrant Spin‐Glass State of MnSb2Te4
Advanced Functional Materials, EarlyView.MnSb2Te4 is an intrinsic magnetic topological insulator. Its properties are extraordinarily sensitive to tiny defects, making structural studies essential for understanding how magnetism and topology work together. This work shows that Mn can be unevenly distributed within the crystal and how that disorder is linked to a newly reported spin‐glass state

On the topology and index of minimal surfaces
Journal of Differential Geometry, 2016 We show that for an immersed two-sided minimal surface in $R^3$, there is a lower bound on the index depending on the genus and number of ends. Using this, we show the nonexistence of an embedded minimal surface in $R^3$ of index $2$, as conjectured by Choe.

On the topological index of irregular surfaces [PDF]
, 2005 We study the topological index of some irregular surfaces that we call generalized Lagrangian. We show that under certain hypotheses on the base locus of the Lagrangian system the topological index is non-negative.

GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching
Advanced Functional Materials, EarlyView.The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays
Advanced Functional Materials, EarlyView.Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Dirac Semimetallicity Enabled by Stripe Antiferromagnetism in Monolayer FeSe
Advanced Functional Materials, EarlyView.In monolayer FeSe, stripe antiferromagnetic order selectively breaks mirror symmetry, enabling odd inter‐orbital hybridization between opposite‐parity Fe 3d states. This mechanism stabilizes symmetry‐protected Dirac nodes with nontrivial Wilson‐loop topology and edge states, accompanied by a strong orbital diamagnetic susceptibility as an experimental ...
