Nondispersing Wave Packets
Abstract
We have formed nondispersing wave packets from atomic Li Rydberg eigenstates by adding a small microwave field approximately resonant with the Δn=1 transition. The orbital motion of the Rydberg electron in states of 70≤n≤78 becomes phase locked to a 17.5GHz microwave field and remains so for 900ns, roughly 15 000 orbits of the Rydberg electron. A Floquet approach provides a reasonable quantum-mechanical description.
