Nonthermal nonlinear many-body excitonic dynamics in high-purity silicon
Patrick Pilch, Siyu Duan, Yang Liu +3
We report time-resolved optical pump-terahertz third-harmonic generation spectroscopy of picosecond nonthermal many-body charge dynamics in high-purity silicon at room temperature.…

Giant enhancement of terahertz high-harmonic generation by cavity engineering of a three-dimensional Dirac semimetal
Siyu Duan, Lili Shi, Patrick Pilch +7
We report on time-resolved ultrafast terahertz high-harmonic generation of strong field driven-dynamics of many-body Dirac fermions. We demonstrate an experimental realization of n…

Terahertz electro-optic Kerr effect in LaAlO3
Sergey Kovalev, Changqing Zhu, Anneke Reinold +9
In this letter, we investigate the terahertz (THz) electro-optic Kerr effect (KE) dynamics in LaAlO3 (LAO), a widely used substrate for thin film preparation. We show that the KE d…
