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.…
Directly probing spin dynamics in insulating antiferromagnets using ultrashort terahertz pulses
P. Bowlan, S. A. Trugman, X. Wang +6
We investigate spin dynamics in the antiferromagnetic (AFM) multiferroic TbMnO3 using optical- pump, terahertz (THz)-probe spectroscopy. Photoexcitation results in a broadband THz…
Electric polarization observed in single crystals of multiferroic Lu2MnCoO6
S. Chikara, J. Singleton, J. Bowlan +5
We report electric polarization and magnetization measurements in single crystals of double perovskite Lu2MnCoO6 using pulsed magnetic fields and optical second harmonic generation…
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…
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…
Time-resolved terahertz dynamics in thin films of the topological insulator BiSe
R. Valdés Aguilar, J. Qi, M. Brahlek +7
We use optical pump--THz probe spectroscopy at low temperatures to study the hot carrier response in thin BiSe films of several thicknesses, allowing us to separate the bul…
