Abstract: The super Efimov effect is a recently proposed three-body effect characterized by a double-exponential scaling, which has not yet been observed experimentally. Here, we present the general dynamic equations determining the cloud size of a scale-invariant quantum gas in a time-dependent harmonic trap. We show that a double-logarithmic periodicity as the hallmark of the super Efimov effect emerges when the trap frequency is decreased with a specially designed time dependence. We also demonstrate that this dynamic super Efimov effect can be realized with realistic choices of parameters in current experiments.
