“…numerical calculation of Hafizi et al using the Klein-Gordon equation [104], is shown. While the theoretical results almost coincide with each other, there is a significant deviation from the numerical calculation especially at high values of I p /c 2 .…”

“…Comparison of the theoretical data for the total probability W T per the laser period with the result of the numerical calculation [104]: via RARM (yellow short-dashed line with squares) with CCSFA of [83] (green long-dashed line with diamonds) using dressed partition, ADK (blue solid line) theories at Z/κ = 1, and (red dash-dotted line with triangles) the numerical calculations via the Klein-Gordon equation [104]. Numerical calculations in [104] have been carried out for the ionization energies I p /c 2 = 0.00866, 0.0351, 0.0809, 0.158, 0.259, using E 0 /E a ≈ 1/16.…”

The analytical R-matrix (ARM) theory has been known for an efficient description of the Coulomb effects of the atomic core in strong-field ionization in the nonrelativistic regime. We generalize the ARM theory into the relativistic domain aiming at the application to strong-field ionization of highly-charged ions in ultrastrong laser fields. Comparison with the relativistic Coulomb-corrected strong field approximations (SFA) is provided, highlighting the advantages and disadvantages. The weakly relativistic asymptotics and its accordance with the nondipole Coulomb-corrected SFA are examined. As an example of a physical application of the relativistic ARM, the Coulomb enhancement of tunneling ionization probability for highly-charged ions at the cutoff of the direct channel is discussed.

“…The polarization of the initial state can be up or down with equal probability. As far as the final state is concerned, one often sums over their polarizations [33,35,[59][60][61]. Here, however, it is the polarization of the photoelectron that is of interest and the summation is not performed.…”

Polarized photoelectrons from converging vector waves

This paper investigates the spin characteristics of photoelectrons when hydrogen-like ions are centro-symmetrically irradiated with converging vector waves – a non-paraxial form of structured light. For a photon with given total angular momentum and third component thereof, photoelectrons with both helicities are obtained – in contrast to the fixed helicities produced by left- or right-circularly polarized light. The angular distribution of photoelectrons is broadly tunable through the radiation mode numbers, and opposite helicities can be extracted in synchronism.
