Ultrafast relaxation of photoexcited superfluid He nanodroplets

M. Mudrich, A. LaForge, F. Stienkemeier +21

The relaxation of photoexcited nanosystems is a fundamental process of light-matter interaction. Depending on the couplings of the internal degrees of freedom, relaxation can be ul…

Carrier dynamics in silicon nanowires studied via femtosecond transient optical spectroscopy from 1.1 to 3.5 eV

Lin Tian, Lorenzo Di Mario, Aswathi K Sivan +5

We present femtosecond transient transmission (or absorbance) measurements in silicon nanowires in the energy range 1.1-3.5 eV, from below the indirect band-gap to above the direct…

Autoionization dynamics of He nanodroplets resonantly excited by intense XUV laser pulses

Y. Ovcharenko, A. LaForge, B. Langbehn +16

The ionization dynamics of helium droplets in a wide size range from 220 to 10^6 He atoms irradiated with intense femtosecond extreme ultraviolet (XUV) pulses of 10^9 ÷ 10^{12} W/c…
