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…
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…
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…
Tracking Charge Migration with Frequency-Matched Strobo-Spectroscopy
Kyle A. Hamer, Aderonke S. Folorunso, Kenneth Lopata +3
We present frequency-matched strobo-spectroscopy (FMSS) of charge migration (CM) in bromobutadiyne, simulated with time-dependent density-functional theory. CM+FMSS is a pump-probe…
Hamiltonian formulation and symplectic split-operator schemes for time-dependent density-functional-theory equations of electron dynamics in molecules
Francois Mauger, Cristel Chandre, Mette B. Gaarde +2
We revisit Kohn-Sham time-dependent density-functional theory (TDDFT) equations and show that they derive from a canonical Hamiltonian formalism. We use this geometric description…
