A research team recently discovered a novel kind of topological edge soliton that is independent of magnetic field. The valley Hall edge soliton inherits its topological protection from its linear ...

Higher-order topological dynamics combines higher-order interactions, topology and non-linear dynamics giving rise to new emergent phenomena. These phenomena encode information which can dramatically ...

Diffraction is a natural property of light beams. It allows light to bend around obstacles. Because light serves as a carrier of information, some of the distorting effects of diffraction must be ...
