Photoionization of atoms and molecules is one of the fastest processes in nature. The
understanding of the ultrafast temporal dynamics of this process often requires the …

Since 2001 and the first demonstrations of the feasibility of generating and measuring
attosecond light pulses, attosecond science has developed into a very active and quickly …

Photons have fixed spin and unbounded orbital angular momentum (OAM). While the former
is manifested in the polarization of light, the latter corresponds to the spatial phase …

A laser-based tabletop approach to femtosecond time-resolved photoelectron spectroscopy
with photons in the vacuum-ultraviolet (VUV) energy range is described. The femtosecond …

Reconstruction of attosecond beating by interference of two-photon transitions (RABBITT) is
an established technique for studying time-delay in photoionization of atoms and molecules …

The angular distribution of photoelectrons ejected during the ionization of Ne atoms by
extreme ultraviolet (XUV) free-electron laser radiation in the presence of an intense near …

The photoelectron angular distribution and the circular dichroism in two-colour XUV+ NIR
above-threshold ionization of helium atoms have been investigated both experimentally and …

Expressions for the angular distribution of photoelectrons produced in two-photon two-color
atomic ionization are obtained within the statistical tensor formalism, taking into account a …

Electron emission caused by extreme ultraviolet (XUV) radiation in the presence of a strong
near infrared (NIR) field leads to multiphoton interactions that depend on several …

Energy-dependent photoelectron angular distributions from two-color two-photon above
threshold ionizations are investigated to determine the partial-wave characteristics of free …
