abstract = {We investigate with exact numerical calculation coherent control of a two-level quantum system{\textquoteright}s decay by subjecting the two-level system to many periodic ideal 2 pi phase modulation pulses. For three spectrum intensities (Gaussian, Lorentzian, and exponential), we find both suppression and acceleration of the decay of the two-level system, depending on difference between the spectrum peak position and the eigen frequency of the two-level system. Most interestingly, the decay of the two-level system freezes after many control pulses if the pulse delay is short. The decay freezing value is half of the decay in the first pulse delay.},
