To solve the Schri+dinger equation with a timedependent Hamiltonian, two main perturbation-expansion schemes arc available: secular averaging theory (SAT) and average Hamiltonian theory (AHT). Due to the lack ofan explicit relationship between SAT and AHT, some discrepancies between the results yiel
