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…

Ultrafast dynamics of vibronically dressed core-excitons in graphite: a femtosecond RIXS perspective
Marco Malvestuto, Beatrice Volpato, Elena Babici +16
This study demonstrates one of the first implementations of time-resolved resonant inelastic X-ray scattering (tr-RIXS), marking a seminal extension of RIXS spectroscopy into the u…
