Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the need for artificially manufactured metamaterials. Scientists have long sought ...

Snell’s law dictates the phenomenon of light refraction at the interface between two media. Here, we demonstrate arbitrary programming of light refraction through an engineered material where the ...

Excitons are prevalent in many bosonic quantum phenomena in semiconductors. During their optical transitions, excitons not only emit or absorb photons, but also determine light propagation behaviours ...
