Abstract

We can identify crystals by their ordering in space, breaking continuous translation symmetry. Analogously, in driven systems the discrete time symmetry of the drive can be broken, leading to a time crystal. We present the direct observation of a space-time crystal exhibiting periodic oscillations in time with double the period of the driving force, and an ordered spatial structure. Due to the small dissipation in our superfluid gas we can study the space-time crystal over an extensive period of time showing the collapse and revival of the oscillating long-lived spatially ordered state.
