Photoionization time delays probe electron correlations
Mingxuan Li, Huiyong Wang, Rezvan Tahouri +16
The photoelectric effect, explained by Einstein in 1905, is often regarded as a one-electron phenomenon. However, in multi-electron systems, the interaction of the escaping electro…
Entanglement Transfer in a Composite Electron-Ion-Photon System
Axel Stenquist, Jakob Nicolai Bruhnke, Felipe Zapata +1
We study how entanglement in photoionization is transferred from an electron-ion pair to an electron-photon pair by fluorescence. Time-resolved von Neumann entropies are used to es…
Frustrated tunneling dynamics in ultrashort laser pulses
Edvin Olofsson, Stefanos Carlström, Jan Marcus Dahlström
We study a model for frustrated tunneling ionization using ultrashort laser pulses. The model is based on the strong field approximation and it employs the saddle point approximati…
Implementation and validation of the relativistic transient absorption theory within the dipole approximation
Felipe Zapata, Jimmy Vinbladh, Eva Lindroth +1
A relativistic transient absorption theory is derived, implemented and validated within the dipole approximation based on the time-dependent Dirac equation. Time-dependent simulati…
Attosecond photoionization dynamics in the vicinity of the Cooper minima in argon
C. Alexandridi, D. Platzer, L. Barreau +15
Using a spectrally resolved electron interferometry technique, we measure photoionization time delays between the and subshells of argon over a large 34-eV energy range c…
Attosecond electron-spin dynamics in Xe 4d photoionization
Shiyang Zhong, Jimmy Vinbladh, David Busto +12
The photoionization of xenon atoms in the 70-100 eV range reveals several fascinating physical phenomena such as a giant resonance induced by the dynamic rearrangement of the elect…
Propensity rules and interference effects in laser-assisted photoionization of helium and neon
Mattias Bertolino, David Busto, Felipe Zapata +1
We investigate the angle-resolved photoelectron spectra from laser-assisted photoionization for helium and neon atoms using an \textit{ab initio} method based on time-dependent sur…
Many-body calculations of two-photon, two color matrix elements for attosecond delays
Jimmy Vinbladh, Jan Marcus Dahlström, Eva Lindroth
We present calculations for attosecond atomic delays in photoionization of noble gas atoms based on full two-color two-photon Random-Phase Approximation with Exchange in both lengt…
Pulse analysis by delayed absorption from a coherently excited atom
Jan Marcus Dahlström, Stefan Pabst, Eva Lindroth
In this tutorial we provide a short review of attosecond pulse characterization techniques and a pedagogical account of a recently proposed method called Pulse Analysis by Delayed…
Attosecond transient absorption of a bound wave packet coupled to a smooth continuum
Jan Marcus Dahlström, Stefan Pabst, Eva Lindroth
We investigate the possibility to use transient absorption of a coherent bound electron wave packet in hydrogen as an attosecond pulse characterization technique. In recent work we…
Intensity Dependence of Laser-Assisted Attosecond Photoionization Spectra
M. Swoboda, J. M. Dahlstrom, T. Ruchon +4
We study experimentally the influence of the intensity of the infrared (IR) probe field on attosecond pulse train (APT) phase measurements performed with the RABITT method (Reconst…
Spectral signature of short attosecond pulse trains
E. Mansten, J. M. Dahlstrom, J. Mauritsson +10
We report experimental measurements of high-order harmonic spectra generated in Ar using a carrier-envelope-offset (CEO) stabilized 12 fs, 800nm laser field and a fraction (less th…
