XUV fluorescence as a probe of interatomic Coulombic decay of resonantly excited He nanodroplets
Keshav Sishodia, Ltaief Ben Ltaief, Niklas Scheel +15
Superfluid He nanodroplets resonantly excited by extreme ultraviolet (XUV) pulses exhibit complex relaxation dynamics, including the formation of metastable excited He atoms tr…
Model-free pattern separation of two-color ultrafast X-ray diffraction
Linos Hecht, Yevheniy Ovcharenko, Asbjørn Ø. Lægdsmand +28
Two-color X-ray imaging with Free Electron Laser pulses offers a powerful approach for probing ultrafast structural dynamics in nanoscale systems, combining (near-)atomic spatial r…
Long-lasting XUV activation of helium nanodroplets for avalanche ionization
C. Medina, A. Ø. Lægdsmand, L. Ben Ltaief +13
We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. In…
Single-shot electron imaging of dopant-induced nanoplasmas
C. Medina, D. Schomas, N. Rendler +19
We present single-shot electron velocity-map images of nanoplasmas generated from doped helium nanodroplets and neon clusters by intense near-infrared and mid-infrared laser pulses…
Ignition of a helium nanoplasma by x-ray multiple ionization of a heavy rare-gas core
D. Schomas, C. Medina, L. Ben Ltaief +14
The dynamics of an x-ray-ionized two-component core-shell nanosystem is probed using doped helium (He) nanodroplets. First, a soft x-ray pump pulse selectively inner-shell ionizes…
Dopant-induced ignition of helium nanoplasmas -- a mechanistic study
Andreas Heidenreich, Dominik Schomas, Marcel Mudrich
Helium (He) nanodroplets irradiated by intense near-infrared laser pulses form a nanoplasma by avalanche-like electron impact ionizations even at lower laser intensities where He i…
Charging dynamics of dopants in helium nanoplasmas
Andreas Heidenreich, Barbara Grüner, Dominik Schomas +3
We present a combined experimental and theoretical study of the charging dynamics of helium nanodroplets doped with atoms of different species and irradiated by intense near-infrar…
Efficiency of Dopant-Induced Ignition of Helium Nanoplasmas
A. Heidenreich, B. Gruener, M. Rometsch +3
Helium nanodroplets irradiated by intense near-infrared laser pulses ignite and form highly ionized nanoplasmas even at laser intensities where helium is not directly ionized by th…
