As far as quantum physics is concerned, one of the most striking predictions is that matter can be produced entirely from light (i.e., photons). Pulsars are an example of an object capable of achieving this feat.In a recent study reported in the journal Physical Review Letters, a research team led by scientists at Osaka University simulated the conditions that allow photons to collide with photons...

A novel method is used to deflect the laser beam using only air. The interdisciplinary research team reported in the journal Nature Photonics that invisible gratings made solely of air not only do not suffer damage from lasers, but also retain the original quality of the beam. The researchers have applied for a patent for their method.Technology and PrinciplesThis innovative technology utilizes so...
