4 v 1 2 9 Se p 19 98 H atom in elliptically polarized microwaves : Semiclassical versus quantum resonant dynamics
The dynamics of Rydberg states of atomic hydrogen illuminated by resonant elliptically polarized microwaves is investigated both semiclassically and quantum mechanically in a simplified two-dimensional model of an atom. Semiclassical predictions for quasienergies of the system are found to be in a very good agreement with exact quantum data enabling a classification of possible types of motion ...

متن کاملResonant dynamics of the H atom in an elliptically polarized microwave field
The dynamics of Rydberg states of atomic hydrogen driven by elliptically polarized microwaves of frequency fulfilling the 2:1 classical resonance condition is investigated both semiclassically and quantum mechanically in a simplified two-dimensional model of an atom. Semiclassical results for quasienergies of the system are shown to be in good agreement with exact quantum data. The structures o...
متن کاملH-atom ionization by elliptically polarized microwave fields: The overlap criterion
The threshold for H-atom ionization by elliptically polarized microwave fields is discussed within the classical-mechanics framework using the Chirikov overlap criterion. It is shown that the trends observed in the recent experiment @M. R. W. Bellermann et al. Phys. Rev. Lett. 76, 892 ~1996!# are qualitatively reproduced by the theory; the origin of the remaining discrepancy is discussed. Incre...
متن کاملStark-state resonances induced by low-frequency elliptically polarized fields
We analyse the effect of a low-frequency elliptically polarized electric field on an excited hydrogen atom using classical dynamics. It is shown that at particular frequencies the ionization probability is a non-monotonic function of the field strength and that at these frequencies the classical ionization probabilities agree well with those of experiment. We show that this unusual behaviour is...
