  • Photoemission is not a simple process and it is not instantaneous. Delays of a few attoseconds have now been measured in helium and it seems that they are partly due to electronic correlations.

  • Microcavities concentrate light in tiny volumes and are important, e.g., for semiconductor lasers and nonlinear optics. In this paper, metasurfaces are introduced to realize microcavities with arbitrary mode profiles.

  • The absolute timing of the photoelectric effect has proved difficult to measure, but the delay between photon arrival at a tungsten surface and ejection of photoelectrons has now been determined.

  • The angular dependence is a well-known issue in metasurface engineering. Here the authors introduce a supercell metasurface able to implement multiple independent functions under large deflection angles with high efficiency, leading to a wavelength tunable laser with arbitrary wavefront control.

  • The miniaturization of optical elements poses challenges for photoacoustic microscopy, where bulky components can hinder performance. The authors utilize meta-optics with sub-wavelength elements to enhance phase control and multifunctionality, demonstrating improved depth of field and performance over conventional lenses, potentially revolutionizing photoacoustic imaging setups.

  • The magnetic properties of a ferromagnetic layer stack are controlled on attosecond timescales through optically induced spin and orbital momentum transfer, demonstrating a coherent regime of ultrafast magnetism.
