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…
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…
All-Electron, Density Functional-Based Method for Angle-Resolved Tunneling Ionization in the Adiabatic Regime
Imam S. Wahyutama, Denawakage D. Jayasinghe, François Mauger +3
We develop and test a method that integrates many-electron weak-field asymptotic theory (ME-WFAT) [Phys. Rev. A 89, 013421 (2014)] in the integral representation (IR) into the dens…
Characterizing Particle-Like Charge Migration Dynamics with High-Harmonic Sideband Spectroscopy
Kyle A. Hamer, Francois Mauger, Aderonke S. Folorunso +5
We introduce high-harmonic sideband spectroscopy (HHSS) and show that it can be a robust probe of attosecond charge migration (CM) in a halogenated carbon-chain molecule. We simula…
Introduction to theory of high-harmonic generation in solids: tutorial
Lun Yue, Mette B. Gaarde
High-harmonic generation (HHG) in solids has emerged in recent years as a rapidly expanding and interdisciplinary field, attracting attention from both the condensed-matter and the…
