New Perturbation Algorithms for Time - Dependent
نویسنده
چکیده
The averaging method for time-dependent quantum systems is used to construct quantum mechanical analogues of the perturbation expansions by Poincar e and by Kolmogorov for time-dependent operators. The resulting two perturbation algorithms are diierent from the usual time-dependent perturbation theory for quantum systems.

متن کاملNonresonant Excitation of the Forced Duffing Equation
We investigate the hard nonresonant excitation of the forced Duffing equation with a positive damping parameter E. Using the symbolic manipulation system MACSYMA, a computer algebra system. we derive the two term perturbation expansion by the method of multiple time scales. The resulting approximate solution is valid for small values of the coefficient e As the damping parameter e increases, th...
