Electron correlations in the antiproton energy loss distribution in He
S. Borbély, X. -M. Tong, S. Nagele +6
We present ab-initio calculations of the electronic differential energy transfer (DET) cross-sections for antiprotons with energies between keV and MeV interacting with heliu…
Polarization tagging of two-photon double ionization by elliptically polarized XUVs
Stefan Donsa, Iva Brezinova, Hongcheng Ni +2
We explore the influence of elliptical polarization on the (non)sequential two-photon double ionization of atomic helium with ultrashort extreme ultraviolet (XUV) light fields usin…
Time delays for attosecond streaking in photoionization of neon
Johannes Feist, Oleg Zatsarinny, Stefan Nagele +5
We revisit the time-resolved photoemission in neon atoms as probed by attosecond streaking. We calculate streaking time shifts for the emission of 2p and 2s electrons and compare t…
Photoionization of helium by attosecond pulses: extraction of spectra from correlated wave functions
Luca Argenti, Renate Pazourek, Johannes Feist +5
We investigate the photoionization spectrum of helium by attosecond XUV pulses both in the spectral region of doubly excited resonances as well as above the double ionization thres…
Nanoplasmonic Lattices for Ultracold atoms
M. Gullans, T. Tiecke, D. E. Chang +5
We propose to use sub-wavelength confinement of light associated with the near field of plasmonic systems to create nanoscale optical lattices for ultracold atoms. Our approach com…
Nanoplasmonic near-field synthesis
Johannes Feist, M. T. Homer Reid, Matthias F. Kling
The temporal response of resonances in nanoplasmonic structures typically converts an incoming few-cycle field into a much longer near-field at the spot where non-linear physical p…
