  • The higher-harmonic generation of laser pulses is used to achieve short-wavelength attosecond pulses for ultrashort experiments, but has been limited in the achievable energy. Here, Ishii et al. develop a scheme to break this barrier and to achieve photon energies higher than the carbon Kedge of about 284 eV.

  • Ultrafast light pulses can manipulate and probe materials faster than relaxation timescales, leading to new electronic states and insights into equilibrium properties. Okazaki et al. use the properties of photo-induced metallic states to investigate unconventional correlated behaviour in Ta2NiSe5 and Ta2NiS5.

  • Ultrafast pulses of terahertz radiation are used to excite individual vibrational modes in a magnetoresistive manganite. In a system such as this, with strongly correlated electrons, even subtle changes of crystal structure can have a profound effect on material properties, and this is indeed what they see: the activated vibration is sufficient to drive the material from a stable insulating phase to a metastable metallic one.

  • Light-matter interactions can be used to induce a superconducting-like state in some cuprate superconductors at temperatures above the expected transition temperature. Here, the authors provide time and angle resolved spectroscopic evidence to suggest that photo induced superconductivity can also be achieved in Fe-based superconductors

  • 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.
