PIConGPU modeling of nanoplasma formation in helium nanodroplets irradiated by intense femtosecond laser pulses
Cristian Medina, Klaus Steiniger, Brian Edward Marre +15
Helium nanodroplets provide a unique and versatile platform for investigating strong-field-driven nanoplasma dynamics. In this work, we present large-scale, GPU-accelerated particl…
Fragmentation of Water Clusters Formed in Helium Nanodroplets by Charge Transfer and Penning Ionization
S. De, A. R. Abid, J. D. Asmussen +6
Helium nanodroplets ("HNDs") are widely used for forming tailor-made clusters and molecular complexes in a cold, transparent, and weakly-interacting matrix. Characterization of emb…
Spectroscopically resolved resonant interatomic Coulombic decay in photoexcited large He nanodroplets
L. Ben Ltaief, K. Sishodia, R. Richter +8
Interatomic Coulombic decay (ICD) processes play a crucial role in weakly bound complexes exposed to intense or high-energy radiation. Using large helium nanodroplets, we demonstra…
