Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.In this work, various topological phases and the bulk‐edge correspondence are studied and established in gyromagnetic photonic Weyl metamaterials. Based on rigorous theoretical analysis, the comprehensive depictions of the multiple topological phase diagrams and multi‐type bulk‐edge correspondences are further mapped out.

On compact Hermitian manifolds with flat Gauduchon connections
, 2017 Given a Hermitian manifold $(M^n,g)$, the Gauduchon connections are the one parameter family of Hermitian connections joining the Chern connection and the Bismut connection.

The Chern-Finsler connection and Finsler-Kähler manifolds
Advanced Studies in Pure Mathematics, 2019 In this paper, we shall discuss the theory of connection in complex Finsler geometry, i.e., the Chern-Finsler connection $\nabla$ and its applications. In particular, we shall investigate (1) the ampleness of holomorphic vector bundles over a compact complex manifold which is based on the study due to [Ko1], (2) some special class of complex Finsler ...

Tunable Topological Directional Supercoupler and Applications in THz On‐Chip Communication
Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.A topological directional supercoupler is demonstrated, enabling dual‐channel 50 Gbps on‐chip terahertz communication with phototunable power splitting ratios. The achieved sub‐wavelength scale coupling area, sharp waveguide bends, and momentum‐conserved coupling process allow for ultra‐compact and efficient terahertz topological photonic integrated ...

Families of singular algebraic varieties that are rationally elliptic spaces
Mathematische Nachrichten, Volume 299, Issue 1, Page 214-223, January 2026.Abstract We discuss families of hypersurfaces with isolated singularities in projective space with the property that the sum of the ranks of the rational homotopy and the homology groups is finite. They represent infinitely many distinct homotopy types with all hypersurfaces having a nef canonical or anti‐canonical class.

Geometry of product complex Cartan manifolds
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 In this paper we consider the product of two complex Cartan manifolds, the outcome being a class of product complex Cartan spaces. Then, we study the relationships between the geometric objects of a product complex Cartan space and its components, (e.g ...

Topological Field Theory and Nonlinear $\sigma$-Models on Symmetric Spaces
, 1995 We show that the classical non-abelian pure Chern-Simons action is related to nonrelativistic models in (2+1)-dimensions, via reductions of the gauge connection in Hermitian symmetric spaces.

FIRE: A Human‐Centered Framework for Digital Twin Design
Systems Engineering, Volume 29, Issue 1, Page 34-48, January 2026.ABSTRACT The integration of human perspectives into digital twin (DT) design for sociotechnical systems (STS) is essential for addressing the complex relationship between social and technical elements. Despite advances in DT technology, its application to STS demands a human‐centered approach that considers usability, user experience, and contextual ...
