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…

Active stabilization for ultralong acquisitions in an attosecond pump-probe beamline
Tamás Csizmadia, Lénárd Gulyás Oldal, Barnabás Gilicze +5
Attosecond time-resolution experiments using noncollinear interferometers require precise and active control of the optical delay to prevent instabilities - including both slow dri…
