  • Here the authors identify real-space contributions to the characteristics of high-harmonic generation in ReS2 and demonstrate the possibility of laser-controlled emission. They find that the spectrum is not just determined by the band structure, but also by the interference between HHG signals coming from different atoms within the unit cell.

  • Attosecond pulses are useful in exploring processes involving ultrafast electron motion in atomic and molecular systems. Here the authors discuss a method to characterize the complex time-varying polarization state of broadband attosecond pulses by using asymmetry in photoelectron spectra.

  • We develop an optical method that can set and read the state of electrons in the valley polarization of bulk transition metal dichalcogenide semiconductors, with potential utility as digital storage at quantum coherent timescales and application in quantum computing.

  • 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.

  • We introduce strong tailored light-wave-driven time-reversal symmetry breaking in monolayer hexagonal boron nitride, realizing a sub-laser-cycle controllable analogue of the topological model of Haldane and inducing non-resonant valley polarization.

  • Analysis of the spread of the 20E (EU1) variant of SARS-CoV-2 through Europe suggests that international travel and insufficient containment, rather than increased transmissibility, led to a resurgence of infections.

  • Whether or not an electron wavepacket accumulates a time delay when tunnelling out of an atom is still under debate. Improved all-optical characterization of the tunnelling dynamics by combining one- and two-colour driving fields may shed light on this question.

  • 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.

  • Ionization time delays are of interest in understanding the photoionization mechanism in atoms and molecules in ultra-short time scales. Here the authors investigate the angular dependence of photoionization time delays in the presence of an autoionizing resonance in argon atom using RABBITT technique.

  • Macias et al. generated a mouse model recapitulating the electrophysiological features of Andersen–Tawil syndrome type 1 (ATS1), a disease associated with life-threatening arrhythmias, via AAV-mediated in vivo expression of trafficking-deficient mutant Kir2.1Δ314-315 channel. The authors identify functional Kir2.1 receptors in sarcoplasmic reticulum (SR) microdomains and report that the ATS1 arrhythmogenic phenotype is due to the dysfunction of Kir2.1 receptors both in the sarcolemma and in the SR domains.

  • 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.
