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…
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…
Powerful and Tunable THz Emitters Based on the Fe/Pt Magnetic Heterostructure
Dewang Yang, Jianhui Liang, Chao Zhou +5
In this work, we report our study on the THz emission in Fe/Pt magnetic heterostructures. We have carried out a comprehensive investigation of THz emission from Fe/Pt magnetic hete…
Mechanical and Electronic Properties of Ferromagnetic GaMnAs Using Ultrafast Coherent Acoustic Phonons
J. Qi, J. A. Yan, H. Park +7
Ultrafast two-color pump-probe measurements, involving coherent acoustic phonon (CAP) waves, have provided information simultaneously on the mechanical properties and on the electr…
