Probing Fermi-surface spin-textures via the nonlinear Shubnikov-de Haas effect
Kazuki Nakazawa, Henry F. Legg, Renato M. A. Dantas +2
The coupling of spin and electronic degrees of freedom via the spin-orbit interaction (SOI) is an essential ingredient for many proposed future technologies. However, probing the s…

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…

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…
