Ultrafast Diffraction from Rydberg Wave Packets Using High Harmonics
Rydberg wave packets have been the object of intense experimental and theoretical study over the past decade due to their many fascinating semiclassical and quantum characteristics. Long-lived wave packets localized in both the radial and angular dimensions have now been produced in alkali metal atoms.1–4 The methods of quantum control can also be applied to calculate the optimally shaped laser pulse which creates a wave packet having a desired distribution in phase space at a specified “target” time.5 Such wave packets can take the form, for instance, of “Schrödinger cat” states,6 or coherent superpositions of macroscopically distinct electronic states.
