    Cold-atom interferometers have been miniaturized towards fieldable quantum inertial sensing applications. Here the authors demonstrate a compact cold-atom interferometer using microfabricated gratings and discuss the possible use of photonic integrated circuits for laser systems.

    Previously, the study of caustics has mostly focused on experiments with light. Here, the authors demonstrate gravitational caustics and investigate catastrophe atom optics using the matter waves of an atom laser generated from a Bose-Einstein condensate.

    Conducting atom-optical experiments in space is interesting for fundamental physics and challenging due to different environment compared to ground. Here the authors report matter-wave interferometry in space using atomic BECs in a sounding rocket.

    Edge states are excitations existing at the boundary of truncated periodic materials with specific spectral degeneracies, and their properties are enriched when materials possess a nonlinear response. Here, the authors provide experimental evidence of edge soliton formation in a nonlinear photonic graphene lattice induced in an atomic vapour cell.

    Quantum coherence and the nonlinear properties of atoms are highly useful in optical devices. Here the authors show quantum-optic hybrid platforms in fully integrated chip-scale atomic diffractive optical elements by embedding hot atomic Rb vapor in microfabricated structures in silicon.

    It is commonly assumed that a complete theory for selection rules in optical nonlinear harmonic generation was developed previously. Here, the authors present more general group theory based formalism for harmonic generation from dilute and dense media, yielding new symmetries and selection rules.

    The rare noble gas isotope 39Ar is the ideal tracer to investigate the ventilation of the deep ocean in the time range of 50 to 1000 years. Here the authors constrain transit time distributions in the eastern Tropical Atlantic with 39Ar-measurements done on a sample size of 5 L of water utilising modern atom-optical techniques.

    Dynamics in cold atomic ensembles involve complex many-body interactions that are hard to treat analytically. Here, the authors use machine learning to optimise the cooling and trapping of neutral atoms, showing an improvement in the resulting resonant optical depth compared to more traditional solutions.

    Field induced tunneling is one of the fundamental processes of light-matter interaction. Here the authors reconstruct the  temporal properties of tunneling using two-color electron holography with attosecond time resolution using argon atoms.

    Studying the effects of quantum coherence and shifts in nanoscale atomic cladding waveguides is challenging. Here, Sternet al. construct a highly compact serpentine silicon-nitride atomic vapour cladding waveguide and observe phenomena such as van-der-Waals shifts, dynamical stark shifts and strong coupling.

    Atom interferometers in microgravity environments can reach precisions unattainable on Earth. Here the authors report the operation of a dual species interferometer onboard a zero-G aircraft, testing universality of free fall in microgravity and providing a test bed for future moving inertial sensors.

    The efficient excitation of atoms using photons is a fundamental step in the control of photon-atom interaction and quantum information protocols. Here the authors show that photons with an exponentially rising envelope excite a single atom efficiently compared to a decaying temporal shape.

    Quantum information processing requires a system in which a single photon controls a single atom and vice versa. Here, the authors demonstrate such reciprocal operation and achieve coherent manipulation of a quantum dot by a few photons sent on an optical cavity.

    Light scattering from a dense coherent medium is determined by the interplay of dispersive and radiative dipole–dipole interactions. Here, the authors control the motional effects that obscure the coherence of scattered light and study collective emission in a driven gas of cold strontium-88 atoms.

    As quantum information technologies develop into practical computational engines, many technical issues must be considered. Devittet al.estimate the resources needed to perform prime factorization with Shor’s algorithm on an atom-optics quantum computer and show how to optimize the computer's performance.

    Atom interferometers exploit wave-particle duality and can be used as sensitive measurement devices. Berrada et al.present a Mach–Zehnder interferometer for Bose–Einstein condensates trapped on an atom chip and demonstrate enhanced performance using non-classical states.
