Ionization suppression of excited atomic states beyond the stabilization regime
Andreas Staudt, Christoph H. Keitel, John S. Briggs
A two-dimensional model atom is employed to study the ionization behavior of initially excited atomic states in highly-frequent intense laser pulses beyond the dipole approximation…
Comparison of classical and second quantized description of the dynamic Stark shift
M. Haas, U. D. Jentschura, C. H. Keitel
We compare the derivation of the dynamic Stark shift of hydrogenic energy levels in a classical framework with an adiabatically damped laser-atom interaction, which is equivalent t…
Laser-dressed vacuum polarization in a Coulomb field
A. I. Milstein, I. S. Terekhov, U. D. Jentschura +1
We investigate quantum electrodynamic effects under the influence of an external, time-dependent electromagnetic field, which mediates dynamic modifications of the radiative correc…
