Abstract
Through both numerical and analytical calculation on quasi-energy bands and corresponding dynamics, it is found that the quasi-energy bands from the particular quasi-momentum can be used to accurately predict the dynamics around that momentum. By suitably selecting the ratio edE/ℏω (E and ω are the strength and frequency of the ac field respectively) to be located around the quasi-energy avoided crossing, coherent destruction of tunneling can be induced, while choosing the ratio edE/ℏω to be away from crossings, Zener tunnelings between two bands arise.
