It is widely believed that periodically driving a generic many-body system will always lead to a featureless state at long times. For high frequencies energy absorption may be parametrically suppressed in the period, but the system nonetheless overheats. Quantum many-body systems, being described by linear equations, may be stroboscopically described by a Floquet Hamiltonian. Non-linear classical systems, however, admit no such description in general. Here we provide evidence that coupling to a reservoir may stabilise, at least on intermediate timescales, a stroboscopic non-equilibrium steady state.
