Two-electron interference in two-photon attosecond double ionization of neon
Siddhartha Chattopadhyay, Carlos Marante, Barry I. Schneider +2
The pump-probe experiments enabled by X-ray free-electron lasers (XFEL) will allow us to directly observe correlated electronic motion with attosecond time resolution by detecting…
Opportunities for Gas-Phase Science at Short-Wavelength Free-Electron Lasers with Undulator-Based Polarization Control
Markus Ilchen, Enrico Allaria, Primož Rebernik Ribič +44
Free-electron lasers (FELs) are the world's most brilliant light sources with rapidly evolving technological capabilities in terms of ultrabright and ultrashort pulses over a large…
Two-photon double ionization with finite pulses: Application of the virtual sequential model to helium
Siddhartha Chattopadhyay, Carlos Marante, Barry Schneider +1
As a step toward the full \emph{ab-initio} description of two-photon double ionization processes, we present a finite-pulse version of the virtual-sequential model for polyelectron…
ASTRA: a Transition-Density-Matrix Approach to Molecular Ionization
Juan Martín Randazzo, Carlos Marante, Siddhartha Chattopadhyay +3
We describe \ASTRA{} (AttoSecond TRAnsitions), a new close-coupling approach to molecular ionization that uses many-body transition density matrices between ionic states with arbit…
