Liquid crystals are substances that flow like a liquid but maintain some of the ordered structure of crystals. Liquid-crystal molecules tend to be elongated and to orient in specific directions.

Scientists created photonic time crystals, unique materials that amplify light and could enhance lasers, sensors, and ...

Crystals and gemstones can be more than just beautiful—they can be deadly. Minerals like arsenopyrite, cinnabar, galena, and torbernite carry toxic substances like arsenic, mercury, lead, and ...

In a new study published in Nature Communications, scientists have implemented the topologically ordered time crystal on a quantum processor for the first time. This marks a new era for quantum ...

The study is published in the journal Nature Photonics. Photonic time crystals represent a unique class of optical materials. Unlike traditional crystals, which have spatially repeating structures ...
