  Simulating physics with large SU(N) symmetry is one of the unique advantages
of Alkaline-earth atoms.Introducing periodical driving modes to the system may
provide more rich SU(N) physics that static one could not reach. However,
whether the driving modes will break the SU(N) symmetry is still lack of
discussions. Here we experimentally study a Floquet engineered degenerate Sr-87
optical lattice clock (OLC) by periodically shaking the lattice. With the help
of Rabi spectroscopy, we find that the atoms at different Zeeman sublevels are
tuned by the same driven function. Meanwhile, our experimental results suggest
that uniform distribution among the sublevels will not change despite the
driving. Our experimental demonstrations may pave the way to implementation of
FE on tailoring the SU(N) physics in OLC system.
