Diffraction of matter waves in space and in time. Atomic wave diffraction and interference using temporal slits. Szriftgiser, P., Guéry-Odelin, D., Arndt, M. This result enables the further exploration of time-varying physics, towards the spectral synthesis of waves and applications such as signal processing and neuromorphic computation. Surprisingly, many more oscillations are visible than expected from existing theory, implying a rise time that approaches an optical cycle. The separation between time slits determines the period of oscillations in the frequency spectrum, whereas the decay of fringe visibility in frequency reveals the shape of the time slits. The ‘time slits’, narrow enough to produce diffraction at optical frequencies, are generated from the optical excitation of a thin film of indium tin oxide near its epsilon-near-zero point. Here we report such a time-domain version of the classic Young’s double-slit experiment: a beam of light twice gated in time produces an interference in the frequency spectrum. Yet, the temporal counterpart of Young’s double-slit experiment-a wave interacting with a double temporal modulation of an interface-remains elusive. Anyone performing any part of these demonstrations, even with revisions, knowingly and voluntarily assumes all risks associated with them.Double-slit experiments-where a wave is transmitted through a thin double aperture in space-have confirmed the wave–particle duality of quantum objects, such as single photons, electrons, neutrons, atoms and large molecules. These risks include, without limitation, bodily injury (and possibly death), including risks to health that may be temporary or permanent and that may exacerbate a pre-existing medical condition and property loss or damage. Performing all or any portion of any of these demonstrations, with or without revisions not depicted here entails inherent risks. The demonstrations included here are within the public domain and can be found in materials contained in libraries, bookstores, and through electronic sources.
