We describe what a time crystal is from the early ideas of spontaneous breaking of time symmetry, and say what a discrete time crystal is.
Then we talk about Google’s recent results claiming observation of a time crystal in a many-body localized state.
The Google arxiv paper:
Previous papers that observed time crystals from 2017:
