Photocurrent-driven transient symmetry breaking in the Weyl semimetal TaAs
N Sirica, P. P. Orth, M. S. Scheurer +23
Symmetry plays a central role in conventional and topological phases of matter, making the ability to optically drive symmetry change a critical step in developing future technolog…
Tracking ultrafast photocurrents in the Weyl semimetal TaAs using THz emission spectroscopy
N. Sirica, R. I. Tobey, L. X. Zhao +14
We investigate polarization-dependent ultrafast photocurrents in the Weyl semimetal TaAs using terahertz (THz) emission spectroscopy. Our results reveal that highly directional, tr…
Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs
B. Xu, Y. M. Dai, L. X. Zhao +12
Strong coupling between discrete phonon and continuous electron-hole pair excitations can give rise to a pronounced asymmetry in the phonon line shape, known as the Fano resonance.…
Optical Signatures of Weyl Points in TaAs
B. Xu, Y. M. Dai, L. X. Zhao +10
We present a systematic study of both the temperature and frequency dependence of the optical response in TaAs, a material that has recently been realized to host the Weyl semimeta…
