Our work on the observation of discrete time-crystalline order in black diamond experiments made the cover of Nature. This work reports the first experimental observation of time-crytalline order together with a concurrent work done in Monroe's group at the University of Maryland. In contrast to the fully controllabe small-size quantum simulator used by Monroe's group, we utilized an ensemble of strongly interacting electronic spin degrees of freedom in diamond to simulate the exotic physics. Chetan Nayak wrote a very nice News & Views article on these complementary works.
