  • Controlling topological photonic quasiparticles is a prerequisite for their implementation in devices. Now, their precise manipulation has been demonstrated using synthetic gauge fields based on the manipulation of the material’s dielectric index.

  • Non-classical correlations between two photons in the near-field regime give rise to entanglement in their total angular momentum, leading to a completely different structure of quantum correlations of photon pairs.

  • On-demand electron wavefront shaping is desirable for applications from nanolithography to imaging. Here, the authors present tunable photon-induced spatial modulation of electrons through their interaction with externally controlled surface plasmon polaritons.

  • Skyrmion bags—textures comprising multiple skyrmions contained within a larger skyrmion—have been reported in several condensed matter systems. Now an optical analogue of these structures has been observed in plasmonic moiré superlattices.

  • Free-electron Ramsey imaging enables space-, time- and phase-resolved electron imaging of weak optical near fields. Owing to its phase-resolving ability, this technique images chiral vortex–anti-vortex phase singularities of phonon-polariton modes in hexagonal boron nitride.

  • A near-field imaging approach based on nonlinear wave mixing that can provide a detailed picture of evanescent waves in real time and with a single shot is demonstrated. Using only standard optical components, this approach will make near-field imaging much more affordable and accessible.

  • The strong interaction of coherent free electrons with a photonic-crystal cavity enables the measurement of the lifetimes of the cavity modes and provides a technique for multidimensional near-field imaging and spectroscopy.

  • While modifications of emission and absorption rates are commonplace in photonics, similar manipulations of emitter transition frequencies are challenging. Here, 2D polaritons in graphene are predicted to enable non-vertical electronic transitions in a quantum well, controlling the transition frequencies by inducing an effective non-locality.
