High-harmonic generation from two weakly coupled molecules: a simple tight-binding model
Lina Bielke, Samuel Schöpa, Falk-Erik Wiechmann +2
The generation of high harmonics is a strongly nonlinear effect that allows to probe properties of the target and to study electron dynamics in matter. It has been investigated in…

Phase structure of below-threshold harmonics in aligned molecules: a few-level model system
Samuel Schöpa, Falk-Erik Wiechmann, Franziska Fennel +1
We utilize few-level model systems to analyze the polarization and phase properties of below-threshold harmonics generated from aligned molecules. In a two-level system, we find th…

High-Order Harmonic Generation in Organic Molecular Crystals
Falk-Erik Wiechmann, Samuel Schöpa, Lina Bielke +6
High-order harmonic generation (HHG) is a powerful tool for probing electronic structure and ultrafast dynamics in matter. Traditionally studied in atomic and molecular gases, HHG…
