  • Bound states in superconducting vortices are expected to exhibit an electron-hole asymmetry, but it is usually tiny and can be easily washed out. Here, the authors show that the vortex bound states coupling to magnetic impurities provides an axial electron-hole asymmetry on a much longer scale, and that the direction of the asymmetry depends on the band character of the superconducting material.

  • 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.

  • By using millikelvin scanning tunnelling microscopy to study atomically flat terraces on U-terminated surfaces of the heavy-fermion superconductor URu2Si2, the two-dimensional heavy fermions are shown to form quantum-well states on the surface.

  • Applications of high temperature superconductors often use layers of materials, and the application of a magnetic field to these layers can generate disk-like pancake vortices within layers crossed with vortices in between layers. The authors present low temperature magnetic force microscopy imaging on a layered superconducting crystal and demonstrate that they are able to manipulate the crossed vortex lattices, hence making this technique an ideal tool for imaging and manipulating superconducting vortices.

  • URu2Si2 is known to exhibit a lower temperature phase transition termed a ‘hidden order’ due to the difficulty its detection using conventional solid-state probes and the exact mechanism still remains unknown. Here, the authors use scanning tunnelling microscopy to reveal a 1D charge density wave for cleaved samples of URu2Si2 and demonstrate a potential connection with the hidden order state.
