Time crystals could perhaps be used to build quantum devices that work at room temperature. Time crystals were long believed to be impossible because they are made from atoms in never-ending motion. The discovery shows that not only can time crystals be created, but they have potential to be turned into useful devices.

A framework of statistical physics can be extended to the nonequilibrium setting to discover previously unidentified phases of matter catalyzed by periodic driving. Scientists aim to reduce the runaway heating associated with driving a strongly interacting quantum system in order to investigate newly discovered phases.
