英文摘要: We study the dynamic behavior of an electron in a two-level system driven by dc-ac electric fields. Analytical solutions for the dipole moment and its emission spectrum are obtained under the approximation of the high-frequency driving case, from which the physical property of the system is found to be controlled by the field parameters. A number of time-periodic and quasiperiodic phenomena as well as their signature in the emission spectrum are revealed. By making the proper choice of the field parameters, it is possible to selectively eliminate some components in the spectrum. The analytical findings are confirmed numerically. [S1050-2947(98)01108-1].
