Photonic crystals are materials in which a periodic variation of the dielectric constant results in a photonic band gap. Photons with wavelengths or energies in this gap cannot travel through the ...

Physicists at the University of Colorado Boulder have created what they call a time crystal: a phase of matter whose parts ...

Scientists observe a visible time crystal for the first time, revealing a phase of matter that repeats patterns through time.

“Most people are familiar with phase transitions like between ice and water, and water and steam,” Outram told Digital Trends. “In some materials, which are common in biological systems, there exist ...

Apatite crystal under a microscope at Paul Fitzgerald’s laboratory at Syracuse University. It was extracted from a granitic rock at the Cauca River Canyon in Colombia. The linear features observed are ...

We expect crystals to be rigid and brittle, so scientists were shocked when some of their crystals seemed to come alive under a microscope. They hope to use the unusual behavior to make tiny machines ...

Big quote: "The whole experience resembles the nerdiest acid trip since Steve Jobs took LSD." Liquid crystal displays are nothing new. In fact, the technology just turned 50-years-old this month ...
