We study the dynamic effect of band electrons in a periodic binary sequence under the action of ac electric fields. Using the technique of the Lie algebra SU(2), we obtain closed-form solutions for the quasienergy and the Floquet states, from which it is found that the evolution behaviour of electrons can be manipulated by the choice of field parameters.
