We prepare a non-interacting 2D gas in a far-from-equilibrium state with a non-thermal momentum distribution that features a sharp UV cutoff and reduced occupation of low-momentum states. To initiate the relaxation dynamics we suddenly turn on the interactions. We observe bidirectional particle and energy conserving relaxation dynamics with self-similar spatiotemporal scaling revealed in the momentum distribution of the cloud.
