Magnetic-order-mediated carrier and phonon dynamics in MnBi2Te4
Liang Cheng, Tian Xiang, Jingbo Qi
We investigate the quasiparticle dynamics in MnBi2Te4 single crystal using the ultrafast optical spectroscopy. Our results show that there exist anomalous dynamical optical respons…
Spintronic Sources of Ultrashort Terahertz Electromagnetic Pulses
Tom S. Seifert, Liang Cheng, Zhengxing Wei +2
Spintronic terahertz emitters are novel, broadband and efficient sources of terahertz radiation, which emerged at the intersection of ultrafast spintronics and terahertz photonics.…
Extremely low-energy collective modes in a quasi-one-dimensional system
Z. X. Wei, S. Zhang, Y. L. Su +5
We have investigated the quasiparticle dynamics and collective excitations in the quasi-one-dimensional material ZrTe using ultrafast optical pump-probe spectroscopy. Our time-…
Chiral terahertz wave emission from the Weyl semimetal TaAs
Y. Gao, Y. Qin, Sahal Kaushik +9
As a fascinating topological phase of matter, Weyl semimetals host chiral fermions with distinct chiralities and spin textures. Optical excitations involving those chiral fermions…
Broadband terahertz generation via the interface inverse Rashba-Edelstein effect
C. Zhou, Y. P. Liu, Z. Wang +8
Novel mechanisms for electromagnetic wave emission in the terahertz (THz) frequency regime emerging at the nanometer scale have recently attracted intense attention for the purpose…
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…
