摘要：

We report the observation of quantum dynamical oscillations of ultracold atomic gases in the F and D bands of an ordinary 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 oscillations comes from a nonadiabatic technique which allows us to load ultracold atoms efficiently to the G band of an optical lattice.
