Real-time simulations of laser-induced electron excitations in crystalline ZnO
Xiao Chen, Thomas Lettau, Ulf Peschel +2
We investigate non-equilibrium electron dynamics in crystalline ZnO induced by ultrashort, relatively intense, infrared laser pulses. Our focus is on understanding the mechanism th…
Light-induced renormalization of the band structure of chiral tellurium
G. Gatti, N. Tancogne-Dejean, H. Hübener +11
Chirality in tellurium derives from a Peierls distortion driven by strong electron-phonon coupling, making this material a unique candidate for observing a light-induced topologica…
Beyond Electric-Dipole Treatment of Light-Matter Interactions in Materials: Nondipole Harmonic Generation in Bulk Si
Simon Vendelbo Bylling Jensen, Nicolas Tancogne-Dejean, Angel Rubio +1
A beyond electric-dipole light-matter theory is needed to describe emerging X-ray and THz applications for characterization and control of quantum materials but inaccessible as non…
Nonlinear photomagnetization in insulators
Bernardo S. Mendoza, Norberto Arzate-Plata, Nicolas Tancogne-Dejean +1
Nonlinear photomagnetization is a process by which an oscillating electric field induces a static magnetization. We show that all 32 crystallographic point groups admit such spin p…
High-harmonic spectroscopy of strongly bound excitons in solids
Simon Vendelbo Bylling Jensen, Lars Bojer Madsen, Angel Rubio +1
We explore the nonlinear response of ultrafast strong-field driven excitons in a one-dimensional solid with ab initio simulations. We demonstrate from our simulations and analytica…
Are there universal signatures of topological phases in high harmonic generation? Probably not
Ofer Neufeld, Nicolas Tancogne-Dejean, Hannes Hübener +2
High harmonic generation (HHG) has developed in recent years as a promising tool for ultrafast materials spectroscopy. At the forefront of these advancements, several works propose…
