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…
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…
Coherent Propagation of Spin Helices in a Quantum-Well Confined Electron Gas
Luyi Yang, J. D. Koralek, J. Orenstein +3
We use phase-resolved transient grating spectroscopy to measure the propagation of spin helices in a high mobility -GaAs/AlGaAs quantum well with an applied in-plane electric fi…
