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

Topological order represents a fundamentally different paradigm of organising matter, one where long‐range entanglement and ground‐state degeneracy are determined by the global properties of the ...

FIG.1. (a) Schematic representation of the third generation of the Sierpinski gasket waveguide arrays with r=0.3a, 0.5a, 0.6a. Blue and orange sectors of these arrays represent the first and ...

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 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 ...
