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…
Probing and controlling terahertz-driven structural dynamics with surface sensitivity
P. Bowlan, J. Bowlan, S. A. Trugman +8
Intense, single-cycle terahertz (THz) pulses offer a promising approach for understanding and controlling the properties of a material on an ultrafast time scale. In particular, re…
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.…
Probing ultrafast spin dynamics in the antiferromagnetic multiferroic HoMnO through a magnon resonance
P. Bowlan, S. A. Trugman, J. Bowlan +5
We demonstrate a new approach for directly measuring the ultrafast energy transfer between elec- trons and magnons, enabling us to track spin dynamics in an antiferromagnet (AFM).…
Probing the Interplay between Quantum Charge Fluctuations and Magnetic Ordering in LuFe2O4
J. Lee, S. A. Trugman, C. D. Batista +7
Ferroelectric and ferromagnetic materials possess spontaneous electric and magnetic order, respectively, which can be switched by the corresponding applied electric and magnetic fi…
