Ultrafast coherent interlayer phonon dynamics in atomically thin layers of MnBi2Te4
F. Michael Bartram, Yu-Chen Leng, Yongchao Wang +10
The atomically thin MnBi2Te4 crystal is a novel magnetic topological insulator, exhibiting exotic quantum physics. Here we report a systematic investigation of ultrafast carrier dy…
Resonant optical topological Hall conductivity from skyrmions
Sopheak Sorn, Luyi Yang, Arun Paramekanti
We study the high frequency Hall conductivity in a two-dimensional (2D) model of conduction electrons coupled to a background magnetic skyrmion texture via an effective Hund's coup…
Anomalous Kerr Effect in SrRuO Thin Films
F. Michael Bartram, Sopheak Sorn, Zhuolu Li +7
We study the magneto-optical Kerr effect (MOKE) in SrRuO thin films, uncovering wide regimes of wavelength, temperature, and magnetic field where the Kerr rotation is not simpl…
Ultrafast spin dynamics in the proximate quantum spin liquid α-RuCl3
Haochen Zhang, Subin Kim, Young-June Kim +2
α-RuCl3 is a Kitaev material suggested to be a proximate quantum spin liquid in a certain temperature and magnetic field range. Nonequilibrium measurements of transient dynamics ha…
Gate controlled spin-valley locking of resident carriers in WSe2 monolayers
P. Dey, Luyi Yang, C. Robert +4
Using time-resolved Kerr rotation, we measure the spin/valley dynamics of resident electrons and holes in single charge-tunable monolayers of the archetypal transition-metal dichal…
Spin coherence and dephasing of localized electrons in monolayer MoS
Luyi Yang, Weibing Chen, Kathleen M. McCreary +3
We report a systematic study of coherent spin precession and spin dephasing in electron-doped monolayer MoS. Using time-resolved Kerr rotation spectroscopy and applied in-plane…
