Displacing Rydberg Electrons: The Mono-Cycle Nature of Half-Cycle Pulses
Journal Article

· Physical Review Letters
A THz 'half-cycle' pulse is a fast (<1 ps ) unipolar pulse, followed by a slow unipolar pulse of opposite polarity. We found that the interaction of such THz pulses with very high Rydberg states results in a displacement of the electron within the atom, while the ionization is strongly suppressed. In classical terms: the first fast unipolar feature corresponds to a start kick of the Rydberg electron, while the second unipolar feature acts as a stop kick. A semiclassical model is presented which qualitatively reproduces the ionization suppression and redistribution.
