For over a century since the Nobel prize winning work by Einstein (1905 Ann. Phys. 17 132),
atomic photoionization was thought to be an instantaneous process. Recent experimental …

Electronic processes within atoms and molecules reside on the timescale of attoseconds.
Recent advances in the laser-based pump-probe interrogation techniques have made …

Circular dichroism (CD) describes the different responses of a chiral object to circularly
polarized light of opposite handedness and serves as the basis of most chirality-sensitive …

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 …

Attosecond chronoscopy is central to the understanding of ultrafast electron dynamics in
matter from gas to the condensed phase with attosecond temporal resolution. It has …

Attosecond photoionization time delays reveal information about the potential energy
landscape that an outgoing electron wavepacket probes upon ionization. In this study, we …

Photoionization of matter is one of the fastest electronic processes in nature. Experimental
measurements of photoionization dynamics have become possible through attosecond …

Characterizing time delays in molecular photoionization as a function of the ejected electron
emission direction relative to the orientation of the molecule and the light polarization axis …

By numerically solving the three-dimensional time-dependent Schrödinger equation, two-
photon ionization of hydrogen is investigated at the near-resonant frequencies of the 1 s-2 p …

Imaging in real time the complete dynamics of a process as fundamental as photoemission
has long been out of reach because of the difficulty of combining attosecond temporal …
