High-order harmonic generation enhanced by XUV light
Christian Buth, Markus C. Kohler, Joachim Ullrich +1
The combination of high-order harmonic generation (HHG) with resonant XUV excitation of a core electron into the transient valence vacancy that is created in the course of the HHG…
Wavelength and intensity dependence of multiple forward scattering at above-threshold ionization in mid-infrared strong laser fields
Chengpu Liu, Karen Z. Hatsagortsyan
The nonperturbative role of multiple forward scattering for Coulomb focusing in mid-infrared laser fields and its dependence on a laser intensity and wavelength are investigated fo…
Transient absorption and reshaping of ultrafast XUV light by laser-dressed helium
Mette B. Gaarde, Christian Buth, Jennifer L. Tate +1
We present a theoretical study of transient absorption and reshaping of extreme ultraviolet (XUV) pulses by helium atoms dressed with a moderately strong infrared (IR) laser field.…
Low-Energy Structures in Strong Field Ionization Revealed by Quantum Orbits
Tian-Min Yan, S. V. Popruzhenko, M. J. J. Vrakking +1
Experiments on atoms in intense laser pulses and the corresponding exact ab initio solutions of the time-dependent Schrödinger equation (TDSE) yield photoelectron spectra with low-…
Phase-matched coherent hard x-rays from relativistic high-order harmonic generation

Photoionization of an atom , in the presence of a neighboring atom , can proceed via resonant excitation of with subsequent energy transfer to through two-center elec…
High Harmonic Generation via Continuum Wave-Packet Interference
Markus C. Kohler, Christian Ott, Philipp Raith +4
High-order harmonic generation (HHG) is investigated theoretically in the over-the-barrier ionization (OBI) regime revealing the strong signature of interference between two separa…
High-energy photoproduction cross section close to the end of spectrum
A. Di Piazza, A. I. Milstein
We consider the cross section of electron-positron pair production by a high-energy photon in a strong Coulomb field close to the end of electron or positron spectrum. We show that…
Symmetric eikonal model for projectile-electron excitation and loss in relativistic ion-atom collisions
A. B. Voitkiv, B. Najjari, S. P. Shevelko
At impact energies GeV/u the projectile-electron excitation and loss occurring in collisions between highly charged ions and neutral atoms is already strongl…
Two-center dielectronic recombination
C. Müller, A. B. Voitkiv, J. R. Crespo López-Urrutia +1
In the presence of a neighboring atom, electron-ion recombination can proceed resonantly via excitation of an electron in the atom, with subsequent relaxation through radiative dec…
