Time delay in nonadiabatic tunneling ionization
Michael Klaiber, Karen Z. Hatsagortsyan, Christoph H. Keitel
The under-the-barrier recollision pathway during the tunneling ionization of an atom, despite its minuscule amplitude, leaves its signature on the observable photoelectron momentum…
Symmetry-Breaking Electron Dynamics Enable Ultrabroadband Optical-Field Sampling via Second-Harmonic Generation
Wenqi Tang, Ahai Chen, Michael Klaiber +4
Optical-field sampling using second-harmonic generation (SHG) from strong-field ionization enables ultrabroadband terahertz detection, but the microscopic origin of the SHG signal…
Role of quantum dynamics in coherent and incoherent radiation during tunneling ionization
Michael Klaiber, Karen Z. Hatsagortsyan, Christoph H. Keitel
Radiation during strong-field tunneling ionization is investigated. The spontaneous as well as the coherent components of the radiation are calculated describing the ionization dyn…
Low-energy photoelectron structures for arbitrary ellipticity of a strong laser field
Q. Z. Lv, M. Klaiber, P. -L. He +2
Previous attoclock experiments measuring the photoelectron momentum distribution (PMD) via strong-field ionization in an elliptically polarized laser field have shown anomalously l…
Atomic polarization and Stark-shift in relativistic strong field ionization
Michael Klaiber, Karen Z. Hatsagortsyan, Christoph H. Keitel
A relativistic analytical theory of strong field ionization applicable across the regimes of the deep-tunneling up to the over-barrier ionization (OTBI) is developed, incorporating…
Relativistic analytical R-matrix (ARM) theory for strong-field ionization
Michael Klaiber, Karen Z. Hatsagortsyan, Christoph H. Keitel
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.…
