Due to come online later this year and packed with state-of-the-art optics, Advanced LIGO is aiming for a direct detection of gravitational waves that will open a new window on the universe, say Iain ...

Dispersive shock waves are a universal phenomenon encountered in many fields of science, ranging from fluid dynamics, Bose-Einstein condensates and geophysics. It has been established that light ...

In modern optics, light can be described at different levels: as rays, as scalar waves, as vector fields, and as quantum fields. In the first three levels, there are singularities—characteristic ...
