We describe a modulated many-body system composed of cold atoms which undergoes spontaneous breaking of the discrete time-translation symmetry. This is induced by the interplay between the interaction and the fluctuation in this nonequilibrium system. From measured critical properties this symmetry-breaking is found to be an ideal meanfield transition. We provide the theoretical model which quantitatively explains the observed critical properties and extends well-known Landau-type meanfield theory.
