Meta-holograms, the computer-generated holograms assisted with nano-structured metasurfaces, promise efficient recording of light at the nanoscale. Adopting the multiplexing principle further bestows ...

(Nanowerk Spotlight) The simplest way to trap light, or in general electromagnetic waves, in a finite region is to realize a region surrounded by mirrors so that light is not able to escape. The ...

The quantum geometric tensor represents a central and ubiquitous concept in quantum mechanics, by characterizing the geometric structure of the Hilbert space. It is responsible to a number of striking ...
