Chern-Simons classes of flat connections on supermanifolds

, 2007
In this note we define Chern-Simons classes of a superconnection $D+L$ on a complex supervector bundle $E$ such that $D$ is flat and preserves the grading, and $L$ is an odd endomorphism of $E$ on a supermanifold. As an application we obtain a definition of Chern-Simons classes of a (not necessarily flat) morphism between flat vector bundles on a ...

Observation of Dislocation Bound States and Skin Effects in Non‐Hermitian Chern Insulators

Advanced Materials, Volume 38, Issue 13, 3 March 2026.
Experimental observation of the dislocation‐induced bound states and skin effects is demonstrated in a line‐gap non‐Hermitian acoustic lattice. By utilizing active meta‐atoms to measure the full complex spectrum and biorthogonal eigenstates, the study reveals the exceptional‐point‐driven melting of defect modes.

Interfaces in Large Area 2D Materials Integration: From Epitaxial Growth and Clean Transfer to Interface‐Dominated Performance

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
This Review proposes an interface‐centric framework for large‐area 2D materials integration, linking wafer‐scale single‐crystal epitaxy, clean transfer and deterministic stacking, and interface‐dominated structure–property–device correlations. We summarize how interfacial symmetry and energetics govern nucleation/coalescence and adhesion‐controlled ...

The connections of pseudo-Finsler spaces

, 2014
We give an introduction to (pseudo-)Finsler geometry and its connections. For most results we provide short and self contained proofs. Our study of the Berwald non-linear connection is framed into the theory of connections over general fibered spaces ...

Effective theories for 2+1 dimensional non-Abelian topological spin liquids

Journal of High Energy Physics, 2017
In this work we propose an effective low-energy theory for a large class of 2+1 dimensional non-Abelian topological spin liquids whose edge states are conformal degrees of freedom with central charges corresponding to the coset structure su(2) k ⊕ su(2 ...

Corrigendum to ``Chern connection of a pseudo-Finsler metric as a family of affine connections" [PDF]

Publicationes Mathematicae Debrecen, 2014
In this note, we give the correct statements of [2,Proposition 3.3 and Theorem 3.4] and a formula of the Chern curvature in terms of the curvature tensor $R^V$ of the affine connection $\nabla^V$ and the Chern tensor $P$.

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

L-infinity algebra connections and applications to String- and Chern-Simons n-transport

, 2008
We give a generalization of the notion of a Cartan-Ehresmann connection from Lie algebras to L-infinity algebras and use it to study the obstruction theory of lifts through higher String-like extensions of Lie algebras. We find (generalized) Chern-Simons

Frobenius 3-Folds via Singular Flat 3-Webs

Symmetry, Integrability and Geometry: Methods and Applications, 2012
We give a geometric interpretation of weighted homogeneous solutions to the associativity equation in terms of the web theory and construct a massive Frobenius 3-fold germ via a singular 3-web germ satisfying the following conditions: 1) the web germ ...

Large Room Temperature Anomalous Nernst Effect Coupled with Topological Nernst Effect from Incommensurate Spin Structure in a Kagome Antiferromagnet

Advanced Science, Volume 13, Issue 17, 23 March 2026.
This study demonstrates that ErMn₆Sn₆, a kagome antiferromagnet hosting incommensurate spin textures, sustains finite scalar spin chirality that drives topological states. The anomalous Nernst effect (ANE) originates from the strong Berry curvature of Chern‐gapped Dirac fermions, while the topological Nernst effect (TNE) arises from emergent fields ...
