  We report on strong renormalization encountered in periodically driven
interacting quantum dots in the non-adiabatic regime. Correlations between lead
and dot electrons enhance or suppress the amplitude of driving depending on the
sign of the interaction. Employing a newly developed flexible renormalization
group based approach for periodic driving to an interacting resonant level we
show analytically that the magnitude of this effect follows a power law. Our
setup can act as a non-Markovian, single-parameter quantum pump.
