Does streaking measure time delays?
ORAL
Abstract
It is rigorously shown under which condition the delay from a streaking spectrogram provides the (Wigner-Smith) time delay. As this is based exclusively on energy absorption, i.\,e.\ the interplay of the binding potential and the streaking laser, it follows immediately that the long-range Coulomb potential is not standing out as the introduction of the so-called ``Coulomb-laser-coupling time'' suggests. A suitable way of defining meaningful (finite) time delays in the case of (long-range) Coulomb potentials is proposed.
