  We report the observation of quantum dynamical oscillations of ultracold
atomic gases in the F and D bands of a single-well optical lattice. We are able
to control the Bragg reflections at the Brillouin zone edge up to the third
order. As a result, we can switch the quantum dynamics from oscillations across
both the F and D bands to oscillations only within the F-band. Our capability
to observe these remarkable oscillations comes from the innovative
non-adiabatic technique which allows us to load ultracold atoms efficiently to
the G-band of an optical lattice.
