Advanced Electronic Materials, EarlyView.Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Benedicks’ theorem for the Heisenberg group [PDF]
Proceedings of the American Mathematical Society, 2010 If $f$ is a compactly supported function on the Heisenberg group and the group Fourier transform $\hat{f}( )$ is a finite rank operator for all $ $ then $f$ is the zero function.

Exceptional Antimodes in Multi‐Drive Cavity Magnonics
Advanced Electronic Materials, EarlyView.Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

The Finite Heisenberg-Weyl Groups in Radar and Communications
EURASIP Journal on Advances in Signal Processing, 2006 We investigate the theory of the finite Heisenberg-Weyl group in relation to the development of adaptive radar and to the construction of spreading sequences and error-correcting codes in communications. We contend that this group can form the basis for

Weak contact equations for mappings into Heisenberg groups
, 2013 Let k>n be positive integers. We consider mappings from a subset of k-dimensional Euclidean space R^k to the Heisenberg group H^n with a variety of metric properties, each of which imply that the mapping in question satisfies some weak form of the ...

Geodesics in the Heisenberg Group
Analysis and Geometry in Metric Spaces, 2015 Abstract We provide a new and elementary proof for the structure of geodesics in the Heisenberg group Hn. The proof is based on a new isoperimetric inequality for closed curves in R2n.We also prove that the Carnot- Carathéodory metric is real analytic away from the center of the group.
