Time-dependent THz dielectric function of ZnTe under two-photon optical excitation at 800 nm wavelength
Farell Keiser, Wentao Zhang, Dominik Johannesmann +5
ZnTe is arguably the most widely used nonlinear crystal for the generation and detection of THz radiation, used in conjunction with sub-bandgap optical excitation by femtosecond la…

Emergent spin Hall conductivity in Tantalum-Rhenium alloys
Felix Janus, Jyoti Yadav, Nicolas Beermann +5
We investigate the spin Hall conductivity (SHC) of a composition series of a Ta-Re bcc solid solution. At approximately 60 at.% Ta the Ta-Re alloy features an SHC similar to bcc-W,…
