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 third-harmonic generation of lightwave driven Weyl fermions far from equilibrium
Patrick Pilch, Changqing Zhu, Sergey Kovalev +4
We report on time-resolved ultrafast terahertz third-harmonic generation spectroscopy of nonequilibrium dynamics of Weyl fermions in a nanometer thin film of the Weyl semimetal TaP…
Quantum spin dynamics of the honeycomb magnet KCoTeO in high magnetic fields
Patrick Pilch, Laur Peedu, Urmas Nagel +6
We present terahertz spectroscopic measurements of quantum spin dynamics in the honeycomb magnet KCoTeO as a function of temperature, polarization and in an external ma…
Distinct terahertz third-harmonic generation of many-body excitonic states
Changqing Zhu, Anneke Reinold, Patrick Pilch +6
The dynamics of an electron-hole plasma governed by strong Coulomb interaction is a challenging many-body problem.We report on experimental realization of electron-hole many-body s…
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…
