Resonant Andreev reflections probed by photon-assisted tunnelling at the atomic scale

Scanning tunnelling microscopy is enhanced by microwave radiation that allows photon-assisted tunnelling processes. This technique is demonstrated on impurity states in a superconductor.

Calorimetry of a phase slip in a Josephson junction

Superconducting currents around a loop containing a weak link can be quantized and only change during discrete events called phase slips. Now, the heat generated by a single phase slip and the subsequent relaxation have been experimentally observed.

Superconductivity in a single-C₆₀ transistor

Single-molecule transistors have enabled studies of magnetism and other correlated nanoscale behaviour, but superconductivity has not been observed with this approach. It is now shown that superconducting junctions on both sides of a C₆₀ molecule induce superconductivity across the whole device.

An epitaxial graphene platform for zero-energy edge state nanoelectronics

Here, the authors show robust edge state transport in patterned nanoribbon networks produced on epigraphene—graphene that is epitaxially grown on non-polar faces of SiC wafers. The edge state forms a zero-energy, one-dimensional ballistic network with dissipationless nodes at ribbon–ribbon junctions.

Imaging tunable quantum Hall broken-symmetry orders in graphene

Three tunable quantum Hall broken-symmetry states in charge-neutral graphene are identified by visualizing their lattice-scale order with scanning tunnelling microscopy and spectroscopy.

Diode effect in Josephson junctions with a single magnetic atom

By analysing atomic-scale Pb–Pb Josephson junctions including magnetic atoms in a scanning tunnelling microscope, a new mechanism for diode behaviour is demonstrated, opening up new paths to tune their properties by means of single-atom manipulation.

Measurement of the inelastic proton–proton cross-section at √s=7 TeV with the ATLAS detector

The measurement of the total cross-section of proton–proton collisions is of fundamental importance for particle physics. Here, the first measurement of the inelastic cross-section is presented for proton–proton collisions at an energy of 7 teraelectronvolts using the ATLAS detector at the Large Hadron Collider.

Joule overheating poisons the fractional ac Josephson effect in topological Josephson junctions

The search for experimental evidence of Majorana modes is an area of intense research in condensed matter and quantum physics and uncovering clear evidence is complicated. The authors investigate the impact of Joule heating which can influence the analysis of experimental features related to Majorana bound states in topological Josephson junctions.
