Abstract
SynopsisAchieving a significant displacement, defined as a time integral of the vector potential taken over the pulse duration, in strong-field atomic ionization critically depends on the envelope function used for the electric field. Due to the sensitivity of theoretical predictions to the pulse details, an experimental realization of the effect appears to be a major challenge.

Synopsis Achieving a significant displacement, defined as a time integral of the vector potential taken over the pulse duration, in strong-field atomic ionization critically depends on the envelope function used for the electric field
The displacement is defined as the time integral of the pulse vector potential taken over the pulse duration, i.e., essentially the second integral over time of the electric field
Further examination [2] of the origin of the displacement, shows that its value critically depends on the assumption of a plateau in the envelope function of the electric field, and that the ramp-on is finetuned, via its length and/or the carrier envelope phase (CEP), in such a way that a drift velocity generated during the ramp-on phase can increase this displacement further
Summary
Synopsis Achieving a significant displacement, defined as a time integral of the vector potential taken over the pulse duration, in strong-field atomic ionization critically depends on the envelope function used for the electric field. Due to the sensitivity of theoretical predictions to the pulse details, an experimental realization of the effect appears to be a major challenge. In a recent paper [1], strong-field ionization of atomic hydrogen as well as lithium driven by a short extreme ultraviolet (XUV) pulse was studied.
