Unraveling Magneto-Phononic Coupling and Photoinduced Magnetic Control in Antiferromagnetic Kondo Semimetal CeBi
Xu-Chen Nie, Chen Zhang, Qi-Yi Wu +9
We report an ultrafast optical spectroscopy study on the coherent phonon dynamics in the topological semimetal CeBi and its nonmagnetic isostructural compound LaBi, revealing profo…
Ultrafast hot carrier dynamics of ZrTe from time-resolved optical reflectivity
Xiu Zhang, Hai-Ying Song, X. C. Nie +8
We investigate the hot carrier dynamics of ZrTe by ultrafast time-resolved optical reflectivity. Our results reveal a phonon-mediated across-gap recombination, consistent with…
Photoinduced two-step insulator-metal transition in Ti4O7 by ultrafast time-resolved optical reflectivity
X. C. Nie, Hai-Ying Song, Xiu Zhang +6
We report on systematic investigation of hot carrier dynamics in Ti4O7 by ultrafast time-resolved optical reflectivity. We find the transient indication for its two-step insulator-…
Study of pseudogap and superconducting quasiparticle dynamics in by time-resolved optical reflectivity
X. C. Nie, Hai-Ying Song, Xiu Zhang +8
The relation between pseudogap (PG) and superconducting (SC) gap, whether PG is a precursor of SC or they coexist or compete, is a long-standing controversy in cuprate high-tempera…
Transient transition from free carrier metallic state to exciton insulating state in GaAs by ultrafast photoexcitation
X. C. Nie, H. Y. Liu, Xiu Zhang +6
We present systematic studies of the transient dynamics of GaAs by ultrafast time-resolved optical reflectivity. In photo excited non-equilibrium states, we found a sign reverse in…
