  • Recently, a Luttinger liquid state was reported in a moiré superlattice of bilayer tungsten ditelluride at small twist angles and temperatures of a few kelvins. Here, the authors extend this result to millikelvin temperatures, supporting the existence of the 2D anisotropic Luttinger liquid as a stable ground state.

  • 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.

  • High-harmonic waves are generated from a MgO crystal under experimental conditions where the simple semi-classical analysis fails. High-harmonic generation spectroscopy directly probes the strong-field attosecond dynamics over multiple bands.

  • 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.

  • The unexpected phenomenon of rapid, long-distance transport of an ultrathin and uniform metal film on two-dimensional crystals is reported at temperatures well below the melting points of all of the materials involved. The effect is generalizable and may offer possibilities in confined space chemistry, as well as in two-dimensional crystal growth and devices.

  • A single-molecule attosecond interferometry that can retrieve the spectral phase information associated with the structure of molecular orbitals, as well as the phase accumulated by an electron as it tunnels out, is demonstrated.

  • 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.

  • Modifications of the effective band structure of MgO crystal is investigated on a timescale within one-quarter cycle of the electromagnetic-field oscillation. The high-harmonic generation spectra show a signature of laser-induced closing of the bandgap.
