RECONFIGURABLE TOPOLOGICAL PHOTONIC CRYSTAL

Reconfigurable topological photonic crystal

Topological insulators are materials that conduct on the surface and insulate in their interior due to non-trivial topology of the band structure.The edge states on the interface between topological (non-trivial) and conventional (trivial) insulators are topologically protected from scattering due to structural defects and disorders.Recently, it wa
