Transient Drude Response Dominates Near-Infrared Pump-Probe Reflectivity in Nodal-Line Semimetals ZrSiS and ZrSiSe
Robert J. Kirby, Austin Ferrenti, Caroline Weinberg +6
The ultrafast optical response of two nodal-line semimetals, ZrSiS and ZrSiSe, was studied in the near-infrared using transient reflectivity. The two materials exhibit similar resp…
Similar ultrafast dynamics of several dissimilar Dirac and Weyl semimetals
Chris P. Weber, Bryan S. Berggren, Madison G. Masten +13
Recent years have seen the rapid discovery of solids whose low-energy electrons have a massless, linear dispersion, such as Weyl, line-node, and Dirac semimetals. The remarkable op…
Transient reflectance of photoexcited CdAs
C. P. Weber, Ernest Arushanov, Bryan S. Berggren +3
We report ultrafast transient-grating measurements of crystals of the three-dimensional Dirac semimetal cadmium arsenide, Cd3As2, at both room temperature and 80 K. After photoexci…
Emergence of the persistent spin helix in semiconductor quantum wells
Jake D. Koralek, Chris Weber, Joe Orenstein +4
According to Noethers theorem, for every symmetry in nature there is a corresponding conservation law. For example, invariance with respect to spatial translation corresponds to co…
Non-diffusive spin dynamics in a two-dimensional electron gas
C. P. Weber, J. Orenstein, B. Andrei Bernevig +3
We describe measurements of spin dynamics in the two-dimensional electron gas in GaAs/GaAlAs quantum wells. Optical techniques, including transient spin-grating spectroscopy, are u…
Observation of spin Coulomb drag in a two-dimensional electron gas
C. P. Weber, N. Gedik, J. E. Moore +3
An electron propagating through a solid carries spin angular momentum in addition to its mass and charge. Of late there has been considerable interest in developing electronic devi…
