We consider a Floquet-engineered model of many-body systems with rapid driving and map the evolutions of the model onto those of relatively slow processes. Such a mapping between rapid and slow evolutions allows us to investigate non-equilibrium many-body dynamics and examine how rapidly driven systems may avoid heating up, at least when mean-field theory is still valid. The fact that the fast time evolution of the system can be mapped exactly onto that of an almost static system suggests that rapid periodic driving does not automatically cause heating, because the system may have a kind of hidden adiabaticity.
