  We propose theoretically how unconventional superconducting pairing in a
repulsively interacting Hubbard ladder can be enhanced via the application of a
Floquet driving. Initially the Hubbard ladder is prepared in its
charge-density-wave dominated ground state. A periodic Floquet drive is applied
which modulates oppositely the energy offset of the two chains and effectively
reduces the tunneling along the rungs. This modulation of the energy offsets
might be caused by the excitation of a suitable phononic mode in solids or a
superlattice modulation in cold atomic gases. We use state-of-the-art density
matrix renormalization group methods to monitor the resulting real-time
dynamics of the system. We find an enormous enhancement of the unconventional
superconducting pair correlations by approximately one order of magnitude.
