    Monatomic glassy antimony can now be achieved via melt-quenching in a nanoconfined volume in a device setting. In contrast to alloys currently used in phase-change memories, deviation from optimized composition is no longer an issue in this simple material.

    Charge order has been established as a ubiquitous instability of the underdoped copper-oxide superconductors. New investigations reveal that it extends to the overdoped side of the phase diagram, a region otherwise known to host a conventional Fermi liquid state.

    Ultracold atoms can model single-order quantum phases, but coupling of different order parameters has not been shown. Here, this is demonstrated using two optical resonators, facilitating exploration of multiple-order systems such as multiferroics.
