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…
