Spin effects in elliptically polarized laser fields in tunnel-ionization — •Enderalp Yakaboylu, Michael Klaiber, and Karen Z. Hatsagortsyan — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany

Spin effects in the tunneling regime of strong field ionization of hydrogenlike highly charged ions in a laser field of elliptical polarization are investigated. The spin-resolved differential ionization rates are calculated employing the dressed relativistic strong-field approximation (SFA), which takes into account the laser driven spin dynamics in the bound state. Analytical expressions for spin asymmetries as well as for the differential probabilities of spin transitions are obtained for the photoelectron momentum corresponding to the maximal tunneling probability. Intuitive explanations for the spin dynamics are provided introducing a simpleman model. The physical relevance of the applied dressed SFA, which is based on a non-standard partition of the total Hamiltonian, is discussed versus the standard SFA.
