Semiclassical two-step model for ionization of hydrogen molecule by strong laser field
N. I. Shvetsov-Shilovski, M. Lein, K. Tőkési
We extend the semiclassical two-step model for strong-field ionization that describes quantum interference and accounts for the Coulomb potential beyond the semiclassical perturbat…
Reciprocal-space-trajectory perspective on high harmonic generation in solids
Liang Li, Pengfei Lan, Xiaosong Zhu +4
We revisit the mechanism of high harmonic generation (HHG) from solids by comparing HHG in laser fields with different ellipticities but constant maximum amplitude. It is shown tha…
Strong-Field Polarizability-Enhanced Dissociative Ionization
Lun Yue, Philipp Wustelt, A. Max Sayler +2
We investigate dissociative single and double ionization of HeH+ induced by intense femtosecond laser pulses. By employing a semi-classical model with nuclear trajectories moving o…
Multielectron polarization effects in strong-field ionization: Narrowing of momentum distributions and imprints in interference structures
N. I. Shvetsov-Shilovski, M. Lein, L. B. Madsen
We extend the semiclassical two-step model [Phys. Rev. A 94, 013415 (2016)] to include a multielectron polarization-induced dipole potential. Using this model we investigate the im…
Double-slit photoelectron interference in strong-field ionization of the neon dimer
Maksim Kunitski, Nicolas Eicke, Pia Huber +13
Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental c…
Heteronuclear Limit of Strong-Field Ionization: Fragmentation of HeH by Intense Ultrashort Laser Pulses
P. Wustelt, F. Oppermann, Lun Yue +6
The laser-induced fragmentation dynamics of this most fundamental polar molecule HeH are measured using an ion beam of helium hydride and an isotopologue at various wavelengths…
