The spontaneous breaking of time-translation symmetry in periodically driven quantum systems leads to a new phase of matter: discrete time crystals (DTC). This phase exhibits collective subharmonic oscillations that depend upon an interplay of non-equilibrium driving, many-body interactions, and the ...
We review the application of discrete time crystals created in a Bose-Einstein condensate (BEC) of ultracold atoms bouncing resonantly on an oscillating atom mirror to the investigation of condensed matter phenomena in the time dimension. Such a bouncing BEC system can exhibit dramatic breaking of t...
In particular, we focus on "discrete time crystals", which are many-body phases of matter characterized by a spontaneously broken discrete time translation symmetry. We give a definition of discrete time crystals from several points of view, emphasizing that they are a non-equilibrium phenomenon, ...
Discrete time-crystals are periodically driven quantum many-body systems with broken discrete time translational symmetry, a non-equilibrium steady state representing self-organization of motion of quantum particles. Observations of discrete time-cr
Time crystals enter the real world of condensed matter Peter Hannaford, a physicist at Swinburne University of Technology in Melbourne, Australia, who was not involved in the research, describes the result as being important for the field of time crystals, as the QuTech-led team unambiguously demo...
An international team of physicists has shown that novel non-equilibrium phases of matter — called prethermal discrete time crystals (DTCs) — can emerge in classical dynamics and do not depend on quantum mechanics. This makes large simulations with relevance to experiments possible. ...

Discrete time crystals attract considerable attention: they are examples of quantum many-body systems that break ergodicity and they are believed to be resistant to decoherence. Moreover, discrete time crystals have been already demonstrated in the laboratory and further experiments are being planned....
