    Ultrashort laser fields applied to a helium dimer are able to tune the interactions between two helium atoms. A video of the dimer’s response to this localized disturbance shows the effect of dissociation and alignment of the wave packets.

    When molecular model systems, such as polycyclic aromatic hydrocarbons, are ionized by ultrashort extreme ultraviolet pulses, their relaxation path proceeds via electron–phonon scattering, linking molecules to typical solid-state matter behaviour.

    Matter-wave interference experiments demonstrate quantum superposition of molecules consisting of up to 2,000 atoms—the heaviest objects to show this quantum behaviour to date. This provides a bound on potential modifications to quantum mechanics.

    The authors study intermolecular Coulomb decay that occurs in a sample of THF and water in a reaction microscope employing triple-coincidence measurements of two ions and one electron. They find that ICD is a previously unconsidered effect between water and other organic molecules that are hydrogen-bonded, with ICD outpacing proton transfer.

    Gravity and quantum mechanics are expected to meet at extreme energy scales, but time dilation could induce decoherence even at low energies affecting microscopic objects—a prospect that could be tested in future matter-wave experiments.
