Scientists experimenting with some of the most fundamental laws of physics have found more evidence of what they're calling photonic time crystals (PTCs): materials in which the speed at which light moves (the refractive index) oscillates very quickly.
A recent study published in the journal Nanophotonics shows that the refractive index, which is the ratio of the speed of electromagnetic radiation in a material to that in a vacuum, can be adjusted quickly enough to produce photonic time crystals (PTCs) in the near-visible region of the spectrum.
