Two-colour coherent control of nuclear and electron dynamics in photoionization of molecular hydrogen with FEL pulses

Fabian Holzmeier, Alberto Gonzalez-Castrillo, Thomas M. Baumann +12

The extension of coherent - control schemes, recently implemented in free-electron lasers (FELs), to molecular systems offers new opportunities to control chemical dynamic…

Breakdown of the isotropic asymptotic approximation in two-colour photoionisation

Sooraj Rajendran, Miguel Benito de Lama, Praveen Kumar Maroju +24

The Wigner delay is defined as the energy derivative of the scattering phase of a particle in a given potential, unveiling the time taken (or gained) due to the interaction. The ch…

Dichroic Electron Emission Patterns from Oriented Helium Ions

Niclas Wieland, Klaus Bartschat, Filippa Dudda +17

We report a joint experimental and theoretical study using a combination of polarization-controlled free-electron-laser (FEL) and near-infra\-red (NIR) pulses in a synchronized two…

Shake-down spectroscopy as state- and site-specific probe of ultrafast chemical dynamics

Henry J. Thompson, Matteo Bonanomi, Jacob Pedersen +27

Tracking the multifarious ultrafast electronic and structural changes occurring in a molecule during a photochemical transformation is a challenging endeavor that benefits from rec…

Unraveling the relaxation dynamics of Uracil: insights from time-resolved X-ray photoelectron spectroscopy

Davide FaccialÃ, Matteo Bonanomi, Bruno Nunes Cabral Tenorio +26

We report a study of the electronic and nuclear relaxation dynamics of the photoexcited RNA base uracil in the gas phase, using time-resolved core level photoelectron spectroscopy…

Relaxation dynamics in excited helium nanodroplets probed with high resolution, time-resolved photoelectron spectroscopy

A. C. LaForge, J. D. Asmussen, B. Bastian +18

Superfluid helium nanodroplets are often considered as transparent and chemically inert nanometer-sized cryo-matrices for high-resolution or time-resolved spectroscopy of embedded…
