Manipulating the Shape of Electronic Non-Dispersive Wave-Packets in the Hydrogen Atom: Numerical Tests in Realistic Experimental Conditions

摘要

We show that combination of a linearly polarized resonant microwave field and a parallel static electric field may be used to create a non-dispersive electronic wavepacket in Rydberg atoms. The static electric field allows for manipulation of the shape of the elliptical trajectory the wavepacket is propagating on. Exact quantum numerical calculations for realistic experi- mental parameters show that the wavepacket evolving on a linear orbit can be very easily prepared in a laboratory either by a direct optical excitation or by preparing an atom in an extremal Stark state and then slowly switch- ing on the microwave field.
