Dynamics of a hydrogen atom under a strong, time-dependent magnetic field

Abstract

The dynamics of a hydrogen atom under a strong, time-dependent, short-frequency magnetic field show a quite interesting parametric resonance behaviour. The present theoretical study reveals very rich features of the interacting system, including the possibility of coherent emission of photons and therefore of a new type of spectroscopy using such magnetic fields. The time scale of the calculated features also suggests new applications in attosecond spectroscopy.
