Résumé :

The development of unitary time-dependent perturbation theories of pulse-driven dynamics was discussed. It was observed that the superexponential perturbation theory based on Kolmogorov-Arnold-Moser (KAM) technique was converged from impulsive to adiabatic regime in two-level systems. It was observed that KAM technique had established the superexponential character and the accuracy optimization. The accuracy optimization which was applied to time-dependent Poincaré-Von-Zeipet, the time-dependent Van Vleck, and the time-dependent KAM technique was also developed and investigated.
