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 ...
Diffusion of waves is a natural result in propagation, like sound, water, and light, while the localization of waves is an unconventional phenomenon in periodic media. It has been an important ...
