Topological crystals are a revolutionary class of materials that exhibit unique electronic and physical properties due to their non-trivial topological band structures. These materials have garnered ...

Topological insulators are strange stuff – the bulk of this material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. This means that charged ...

Researchers demonstrate that the phenomenon of the dynamic coupling of thermally activated skyrmions to chiral flowers can pave the way for a topological sorting device. In nature, the collective ...

Chiral skyrmions are a special type of spin textures in magnetic materials with asymmetric exchange interactions. They can be treated as quasi-particles and carry integer topological charges.

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...
