Strong-field approximation for harmonic generation in diatomic molecules
Ciprian C. Chirila, Manfred Lein
The generation of high-order harmonics in diatomic molecules is investigated within the framework of the strong-field approximation. We show that the conventional saddle-point appr…
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…
Magnetic-dipole transition probabilities in B-like and Be-like ions
I. I. Tupitsyn, A. V. Volotka, D. A. Glazov +5
The magnetic-dipole transition probabilities between the fine-structure levels (1s^2 2s^2 2p) ^2P_1/2 - ^2P_3/2 for B-like ions and (1s^2 2s 2p) ^3P_1 - ^3P_2 for Be-like ions are…
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…
Mass Measurements and the Bound--Electron g Factor
U. D. Jentschura, A. Czarnecki, K. Pachucki +1
The accurate determination of atomic masses and the high-precision measurement of the bound-electron g factor are prerequisites for the determination of the electron mass, which is…
Techniques in Analytic Lamb Shift Calculations
U. D. Jentschura
Quantum electrodynamics has been the first theory to emerge from the ideas of regularization and renormalization, and the coupling of the fermions to the virtual excitations of the…
Self-energy values for P states in hydrogen and low-Z hydrogenlike ions
U. D. Jentschura, P. J. Mohr
We describe a nonperturbative (in Zalpha) numerical evaluation of the one-photon electron self energy for 3P_{1/2}, 3P_{3/2}, 4P_{1/2} and 4P_{3/2} states in hydrogenlike atomic sy…
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…
QPROP: A Schroedinger-solver for intense laser-atom interaction
D. Bauer, P. Koval
The Qprop package is presented. Qprop has been developed to study laser-atom interaction in the nonperturbative regime where nonlinear phenomena such as above-threshold ionization,…
Complete two-loop correction to the bound-electron g factor
Krzysztof Pachucki, Andrzej Czarnecki, Ulrich D. Jentschura +1
Within a systematic approach based on the dimensionally regularized nonrelativistic quantum electrodynamics, we derive the complete result for the two-loop correction to order $(α/…
Emergence of Classical Orbits in Few-Cycle Above-Threshold Ionization
D. Bauer
The time-dependent Schrödinger equation for atomic hydrogen in few-cycle laser pulses is solved numerically. Introducing a positive definite quantum distribution function in energy…
