  • 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.

  • Light absorption in matter often induces ultrafast electron dynamics within the system. Here, the authors record a femtosecond movie of the electron density of an argon ion as it oscillates in a quantum beat of two fine-structure states.

  • Understanding light-matter interaction is important for the control of energy and charge transfer at the fundamental level. Here the authors spatially resolve proton generation in laser-induced dissociative ionization of ethanol and water on SiO2 nanoparticles and discuss the role of surface charge distribution.

  • A solid-state device is demonstrated that can detect the absolute offset between the carrier wave and envelope of an ultrashort pulse, the carrier–envelope phase. It holds promise for routine measurement and monitoring of the carrier–envelope phase in attosecond experimental set-ups.

  • Conical intersections, a hallmark of polyatomic molecules, can be induced with light, leading to new reaction pathways. Here, the authors show that intense fields can create complex, beyond-conical intersections even in diatomics, resulting in an unexpected angular distribution of fragment ions.
