May issue

This month we demonstrate coherent control of a multi-qubit dark state, examine the Fermi surface in cuprates, and say farewell to our Letter format.


  • Ultracold quantum technologies

    The impressive achievements made with quantum gases rely on continuous improvements in the underlying methods. This Insight reviews recent technological advances that have deepened and broadened the capabilities of ultracold gas experiments

  • The mechanism that drives nematic behaviour in iron-based superconductors is still unclear. Now, nematicity and anisotropy in spin excitations are shown to disappear at the same temperature, indicating that the transition is primarily spin-driven.

  • The concept of quasi-symmetry—a perturbatively small deviation from exact symmetry—is introduced and leads to topological materials with strong resilience to perturbations.

  • Electrical readout of the state of an antiferromagnet is an important goal for spintronic applications. Now, detection of the electrical voltage created by a thermal gradient in a canted antiferromagnet suggests a route for achieving this goal.

    • The appearance of small local gaps in the electronic band structure of a topological semimetal is attributed to a hidden quasi-symmetry that produces a large Berry curvature.

    • An experimental realization of an artificial spin glass is demonstrated, with an arrangement of Ising-type permalloy nanomagnets mimicking the structure of artificial spin ice — and a particular type of neural network.

    • Biomolecular condensates grow in busy cellular environments. Statistical image analysis of heterogeneous structures now enables quantification of macromolecular interactions between condensates and cytoskeletal filaments.

  • As conventions in scholarly publishing evolve, it is appropriate to reassess the options that we provide to our authors. In this spirit, Nature Physics will soon stop accepting submissions in our Letter format.

  • Progress in research would be impossible without state-of-the art instruments, but their contributions are often underappreciated.

  • Juris Meija takes a look at the tumultuous past of the atomic unit of mass from its beginnings as an idea to its most recent revisions in a hotel bar.
