  • Superoscillations enable waves to oscillate faster beyond classical limits. Here, the authors demonstrate simultaneous spatial and temporal superoscillations in structured light pulses, achieving extreme both subwavelength and ultrafast focusing in space-time.

  • Topological waves and their exotic properties are attracting intense research interest. Here, the authors report on the discovery of supertoroidal electromagnetic pulses with robust skyrmionic topology that persists upon propagation over arbitrarily long distances.
