Prediction of Spin Polarized Fermi Arcs in Quasiparticle Interference of CeBi
Zhao Huang, Christopher A. Lane, Chao Cao +8
We predict that CeBi in the ferromagnetic state is a Weyl semimetal. Our calculations within density functional theory show the existence of two pairs of Weyl nodes on the momentum…
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…
Ultrafast Polaron Dynamics in Layered and Perovskite Manganites: 2D and 3D Polarons
J. Lee, H. J. Lee, R. D. Averitt +8
We have studied the sub-picosecond quasiparticle dynamics in the perovskite manganite La0.7Ca0.3MnO3 and the layered manganite La1.4Sr1.6Mn2O7 using ultrafast optical spectroscopy.…
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).…
Hall effect in the extremely large magnetoresistance semimetal WTe
Yongkang Luo, H. Li, Y. M. Dai +7
We systematically measured the Hall effect in the extremely large magnetoresistance semimetal WTe. By carefully fitting the Hall resistivity to a two-band model, the temperatur…
