Localized intrinsic bond orbitals decode correlated charge migration dynamics
Imam S. Wahyutama, Madhumita Rano, Henrik R. Larsson
For decades, scientists have studied the intricate charge migration dynamics, where after ionization a localized charge distribution ("hole") migrates across the molecule on a femt…
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…
Simulating real-time molecular electron dynamics efficiently using the time-dependent density matrix renormalization group
Imam S. Wahyutama, Henrik R. Larsson
Compared to ground state electronic structure optimizations, accurate simulations of molecular real-time electron dynamics are usually much more difficult to perform. To simulate e…
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…
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…
Attochemistry Regulation of Charge Migration
Aderonke S. Folorunso, François Mauger, Kyle A. Hamer +8
Charge migration (CM) is a coherent attosecond process that involves the movement of localized holes across a molecule. To determine the relationship between a molecule's structure…
Time-Dependent Multiconfiguration Self-Consistent-Field Study on Resonantly Enhanced High-Harmonic Generation from Transition Metal Elements
Imam S. Wahyutama, Takeshi Sato, Kenichi L. Ishikawa
We theoretically study high-harmonic generation (HHG) from transition metal elements Mn and Mn, using full-dimensional, all-electron, first-principles simulations. The HHG spec…
High Speed and High Resolution Table-Top Nanoscale Imaging
G. K. Tadesse, R. Klas, S. Demmler +8
We present a table-top coherent diffraction imaging (CDI) experiment based on high-order harmonics generated at 18 nm by a high average power femtosecond fiber laser system. The hi…
