Abstract: | The effects of an applied low frequency field on the
dynamics of a two-level atom interacting with a single-mode field
are investigated. It is shown that the time evolution of the atomic
population is mainly controlled by the coupling constants and the
frequency of the low frequency field, which leads to a low frequency
modulation function for the time evolution of the upper state
population. The amplitude of the modulation function becomes larger
as the coupling constants increase. The frequency of the modulation
function is proportional to the frequency of the low frequency
field, and decreases with increasing coupling constant. |
