Femtosecond Nonadiabatic Confinement of Molecular Dication Yield

Carlos Marante, Lina Fransén, Alexie Boyer +5

Doubly charged molecular cations often carry signatures of electronic correlation and electron-nuclear entanglement present in the parent cation. Here, we produce ethylene dication…

The influence of final state interactions in attosecond photoelectron interferometry

Sizuo Luo, Robin Weissenbilder, Hugo Laurell +14

Fano resonances are ubiquitous phenomena appearing in many fields of physics, e.g. atomic or molecular photoionization, or electron transport in quantum dots. Recently, attosecond…

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…

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…

Measuring autoionization decay lifetimes of optically forbidden inner valence excited states in neon atoms with attosecond noncollinear four wave mixing spectroscopy

Nicolette G. Puskar, Yen-Cheng Lin, James D. Gaynor +8

Attosecond noncollinear four wave mixing spectroscopy with one attosecond extreme ultraviolet (XUV) pulse and two few-cycle near-infrared (NIR) pulses was used to measure the autoi…

ASTRA, A Transition Density Matrix Approach to the Interaction of Attosecond Radiation with Atoms and Molecules

Juan M Randazzo, Carlos Marante, Siddhartha Chattopadhyay +4

A new formalism and computer code, ASTRA (AttoSecond TRAnsitions), has been developed to treat the interactions of short, intense radiation with molecules. The formalism makes exte…
