  • Attosecond metrology in vacuum-ultraviolet. The study demonstrates vacuum-ultraviolet attosecond pulse generation in laser-driven semiconductors and a new spectral window for attosecond spectroscopy in natural systems across all states of matter.

  • The high harmonic emission that accompanies the recombination of an electron with its parent molecular ion in an intense laser field provides a snapshot of the structure and dynamics of the recombining system. Experiments on CO2 molecules now show how to extract information from the properties of the emitted light about the underlying multi-electron dynamics with sub-Ångström spatial resolution and attosecond temporal resolution

  • Here, the authors show the emergence of valley-polarized Floquet-Bloch states in 2H-WSe2 upon below-band-gap driving using circularly polarized light.

  • A method of laser-induced recollision permits measurement with attosecond resolution of the times at which the electron leaves the tunnelling barrier and discriminates between the ionization times of two carbon dioxide orbitals.

  • Sub-cycle phase-resolved attosecond interferometry is developed. The obtained phase information enables us to decouple the multiple quantum paths induced in a light-driven system, isolating their coherent contribution and retrieving their temporal evolution.

  • Time-resolved photoelectron circular dichroism with a temporal resolution of 2.9 fs is used to track the ultrafast electron dynamics following ultraviolet excitation of neutral chiral molecules, which generate chiral currents that exhibit periodic rotation direction reversal.

  • A time-domain approach that can continuously tune the polarization state of extreme-ultraviolet attosecond pulses allows the isolation and amplification of extremely weak chiral signals, extending vectorial measurements to the attosecond and nanometre scales.

  • The absolute phase difference of the harmonic emission of Ar, Ne and He atoms is measured by XUV interferometry with temporal resolution of 6 as. This measurement provides a direct insight into the quantum properties of the photoelectron wavefunctions.
