    A new type of skyrmion is identified in the chiral magnetic material Cu2OSeO3 at low temperature. This is the first time that a single material has been shown to exhibit more than one distinct skyrmion phase.

    Biofilms of rod-shaped bacteria can grow from a two-dimensional layer of founder cells into a three-dimensional structure with a vertically aligned core. Here, the physics underlying this transition is traced down to the properties of individual cells.

    By coupling photons in two distinguishable modes to separate transitions of a single atom, strong correlations between photons are created. The technique makes all-optical switching and sensing possible at the single-photon level.

    Applications of spintronics often require angular momentum to be moved from place to place. A possible observation of spin superfluidity may point the way toward the transport of spin angular momentum across an insulating sample with no dissipation or energy loss.

    Spins are transmitted over a distance of 5 μm through a piece of antiferromagnetic graphene. This shows that graphene can be a platform to explore the fundamental physics of spin transport in antiferromagnets for application in spintronics.

    A superlattice consisting of SrIrO3 and SrTiO3 is shown to display a giant response to sub-tesla external magnetic fields—a direct consequence of its antiferromagnetic nature.

    Energy levels in superconducting quantum devices are highly sensitive to charge fluctuations. Generally, this is considered a bug, but new work transforms this sensitivity into the defining feature of a novel device.
