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

Topological superconductors are materials that, beyond simply exhibiting superconductivity, possess a topological order. This order refers to the global properties of the material's wavefunctions that ...

Topological phases are at the heart of many advances in photonics and materials science. In a recent eLight paper, researchers introduced the concept of multi-topological phases, a previously unknown ...
