It is remarkable that time delay is an experimentally measurable quantity, but time itself is
not. Time delay in quantum collisions and in photoionisation/photodetachment of atomic and …

We report on the energy dependence of the photoemission time delay from the single-
element layered dielectric HOPG (highly oriented pyrolytic graphite). This system offers the …

Photoionization of acetylene by extreme ultraviolet light results in a stand-alone contribution
from the outermost valence orbital, followed by well-separated photoelectron bands from …

Recent development of ultrafast measurement techniques on the sub-femtosecond time
scale has enabled us to see the atom–laser interaction in real time. One of the important …

We investigate signatures of anisotropy on the dynamics of time-resolved near-threshold
molecular photoemission through simulations on a one-dimensional asymmetric model …

We review various aspects of photoemission dynamics in the case of two-photon ionisation.
We first recall the definition of a transition phase specific to two-photon transitions …

Confined atomic systems are of great importance owing a multitude of possible applications
in various areas of science and technology. Of particular interest are atoms encaged in the C …

The natural diversity of molecules in terms of geometries, chemical properties, work
functions, among others, offers an impressive laboratory for observing fundamental electron …

Coulomb confinement resonances (CCRs) are the main features of the photoionization
spectra of an atom inside an anionic fullerene. These CCRs can act as an amplifier to spin …

We study the photoionization properties of the C 60 versus C 240 molecule in a spherical
jellium frame of the density-functional method. Two prototypical approximations of the …
