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 ...

For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. This finding opens up a new range of possibilities for the development of efficient ...
