  • 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.

  • 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 Berry phase is resolved in light-driven crystals, via attosecond interferometry, in which the electronic wavefunction accumulates a geometric phase as it interacts with the laser field, mapping its coherence into the emission of high-order harmonics.

  • Attosecond-gated interferometry is developed by combining sub-cycle temporal gating and extreme-ultraviolet interferometry. By measuring the electron’s relative phase and amplitude under a tunnelling barrier, the quantum nature of the electronic wavepacket is identified.

  • 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.
