Orbital distortion and parabolic channel effects transform minima in molecular ionization probabilities into maxima
Imam S. Wahyutama, Denawakage D. Jayasinghe, Francois Mauger +2
In the tunneling regime and at sufficiently low field amplitudes, the shape of orientation-dependent molecular ionization rate curves usually resembles the shape of the ionized orb…
All-Electron Molecular Tunnel Ionization Based on the Weak-Field Asymptotic Theory in the Integral Representation
Imam S. Wahyutama, Denawakage D. Jayasinghe, Francois Mauger +2
Tunnel ionization (TI) underlies many important ultrafast processes, such as high-harmonic generation and strong-field ionization. Among the existing theories for TI, many-electron…
Quantitative comparison of TDDFT-calculated HHG yields in ring-shaped organic molecules
Stephanie N. Armond, Kyle A. Hamer, Ravi Bhardwaj +4
We compare the high-harmonic-generation (HHG) yield driven by a mid-infrared laser in three organic ring-shaped molecules, calculated using time-dependent density-functional theory…
Strong-field ionization with few-cycle, mid-infrared laser pulses induces a localized ionization followed by long-lasting charge migration in halogenated organic molecules
Kyle A. Hamer, Francois Mauger, Kenneth Lopata +2
We show that applying a few-femtosecond mid-infrared laser pulse parallel to the backbone of a halogenated, conjugated organic molecule induces localized ionization followed by lon…
