Query: Spatio-temporal delay in photoionization by polarization structured
  laser fields   Focused laser fields with textured polarization on a sub-wavelength scale
allow extracting information on electronic processes which are not directly
accessible by homogeneous fields. Here, we consider photoionization in radially
and azimuthally polarized laser fields and show that, due to the local
polarizations of the transversal and the longitudinal laser electric field
components, the detected photoelectron spectra depend on the atom position from
which the electron originates. The calculation results reported here show the
angular dependence of the photoionization amplitude, the quantum phase, and the
time delay of the valence shell electrons as the parent atom's position varies
across the laser spot. We discuss the possibility of using the photoelectron
spectra to identify the position of the ionized atom within the laser spot on
the sub-wavelength scale. The proposal and its illustrations underline the
potential for the detection of the atomic position based on attosecond
streaking methods.
