    Physicists are searching for superconducting materials that can host Majoranas. New evidence for these elusive particles is provided by missing Shapiro steps in a Josephson effect mediated by an accidental Dirac semimetal.

    The metallic state of an iron chalcogenide superconductor is demonstrated to be characterized by the simultaneous presence of itinerant carriers with different degrees of correlation. This orbital-selective metal arises from a sizeable Hund’s coupling.

    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.
