  • Due to their small size, atomic-scale Josephson junctions are vulnerable to thermal fluctuations. Escribano et al. show that introducing a delayed feedback element, a common method to mitigate thermal noise, induces spontaneous oscillations that enhance capabilities of Josephson microscopy.

  • Electron pairing is of fundamental interest in condensed matter physics. Here, the authors demonstrate electrons forming not only pairs - but also triplets - in graphene quantum Hall Fabry-Pérot interferometers.

  • A first-order, disorder-driven, superconductor–insulator phase transition is demonstrated. This is in contrast with the usually observed second-order transition and highlights the role of Coulomb interactions between preformed Cooper pairs.

  • Proximity effects enable superconductivity to leak into normal metals. In graphene, a Klein-like tunnelling of superconducting pairs from a high-temperature superconductor allows the proximity effects to be tuned by electric fields.
