Ultrafast dynamics in normal and Charge Density Wave phase of 2H-NbSe2
A. Anikin, R. D. Schaller, G. P. Wiederrecht +3
We investigate carrier and collective mode dynamics in 2H-NbSe using time-resolved optical pump-probe spectroscopy and compare the results with first-principle calculations. Br…
Unconventional slowing down of electronic recovery in photoexcited charge-ordered LaSrFeO
Yi Zhu, Jason Hoffman, Clare E. Rowland +7
Ordered electronic phases are intimately related to emerging phenomena such as high Tc superconductivity and colossal magnetoresistance. The coupling of electronic charge with othe…
Ultrafast Dynamics of the Charge Density Wave State in Layered CuxTiSe2
D. B. Lioi, R. D. Schaller, G. P. Wiederrecht +1
We report on a transient optical reflectivity study of the charge density wave (CDW) in CuxTiSe2 single crystals. Our measurements reveal that the system undergoes a quantum phase…
Structural and Electronic Recovery Pathways of a Photoexcited Ultrathin VO2 Film
Haidan Wen, Lu Guo, Eftihia Barnes +10
The structural and electronic recovery pathways of a photoexcited ultrathin VO2 film at nanosecond time scales have been studied using time-resolved x-ray diffraction and transient…
