Periodically-driven systems present a special class of out-of-equilibrium systems. While the dynamics in these models can be fully described from Floquet theory, similar to Bloch theory in periodic lattices, any practical application of this theory in many-body systems is hindered by the exponentially large Hilbert space. Here, we show how the use of integrable Hamiltonians in the driving protocol may give rise to a tractable Floquet theory, with special attention paid to the appearance of so-called Floquet of many-body resonances. This is applied to a driven central spin, where it is shown how periodic driving and resonances can be used to construct pure spin states.
