  • The momentum and spin of a propagating photon are given by its wave vector and circular polarization, respectively. Bliokh et al.here show that evanescent electromagnetic waves possess a polarization-dependent momentum component and a polarization-independent spin component, which are both orthogonal to the wave vector.

  • The spin Hall effect, an interaction between particles because of their intrinsic spin, is a central tenet in the field of spintronics. The direct observation of an optical equivalent of the spin Hall effect is now reported.

  • Interference of linear plane waves produces non-trivial phenomena in both classical and quantum wave systems. Here, the authors describe and observe anomalously large time delays and frequency shifts in the resonant inelastic scattering of a 1D wave packet near a zero of the scattering coefficient.

  • Electromagnetic surface waves, derived from Maxwell theory, underpin many optical effects and applications. Here, Bliokh et al. show that surface waves at interfaces between isotropic media have a topological origin described by the non-Hermitian helicity operator and bulk-boundary correspondence.

  • Landau states are associated with the quantised orbits of charged particles in magnetic fields. By manipulating electron vortex beams in a magnetic field, this study reconstructs the internal quantum dynamics of free-electron Landau states, which differs strongly from the classical cyclotron rotation.

  • A theoretical and experimental study of the transverse spin appearing in non-paraxial light when the source is totally unpolarized is reported, in sharp contrast to the usual longitudinal spin, which is directly related to the 2D polarization and vanishes in unpolarized fields.

  • This Review article provides an overview of the fundamental origins and important applications of the main spin–orbit interaction phenomena in modern optics that play a crucial role at subwavelength scales.

  • In non-Hermitian systems, spectral degeneracies can arise that can cause unusual, counter-intuitive effects; here exciton-polaritons—hybrid light–matter particles—within a semiconductor microcavity are found to display non-trivial topological modal structure exclusive to such systems.
