Entanglement in photoionisation reveals the effect of ionic coupling in attosecond time delays

The authors report on an experimental study of attosecond time delays of photoelectrons emitted from CO₂ molecules. This clarifies the role of internal dynamics of ions and ionelectron entanglement on the photoionization dynamics.

Imaging an aligned polyatomic molecule with laser-induced electron diffraction

Laser-induced electron diffraction can provide structural information on gas-phase molecules with high spatial and temporal resolution. Going beyond previous diatomic cases, Pullen et al.apply this approach to acetylene and show that it can be used to measure bond lengths for polyatomic molecules.

Attosecond tracing of correlated electron-emission in non-sequential double ionization

Studying the dynamics of electrons is important for understanding fundamental processes in materials. Here the ionization of a pair of electrons in argon atoms is explored on attosecond timescales, offering insight into their correlated emission and the double ionization mechanism.

Ultra-efficient ionization of heavy atoms by intense X-ray free-electron laser pulses

Researchers create high ionization states, up to Xe³⁶⁺, using 1.5 keV free-electron laser pulses. The higher than expected ionization may be due to transient resonance-enhanced absorption and the effect may play an important role in interactions of intense X-rays with high-Z elements and radiation damage.

Symmetry-breaking dynamics of a photoionized carbon dioxide dimer

In a time-resolved Coulomb explosion imaging study using ultrafast extreme ultraviolet pulses, combined with theoretical simulations, authors reveal unexpected asymmetric rearrangement of carbon dioxide dimer ion, including a CO₃ moiety formation.

Reconstruction and control of a time-dependent two-electron wave packet

The dynamics of two correlated electrons can be reconstructed from the quantum interference of low-lying doubly excited states in helium, as observed in attosecond transient-absorption spectra, and can be controlled by tuning the interaction with a visible laser field of variable intensity.
