Multi-terminal Josephson junctions as topological matter
Topological materials and their unusual transport properties are now at the focus of modern experimental and theoretical research. Their topological properties arise from the bandstructure determined by the atomic composition of a material and as such are difficult to tune and naturally restricted to ≤3 dimensions. Here we demonstrate that n-terminal Josephson junctions with conventional superc...
متن کاملAndreev-level spectroscopy and Josephson-current switching in a three-terminal Josephson junction
We calculate the electrical currents through a superconductor-insulator-superconductor junction which is also weakly coupled to a normal-metal side probe. The voltage V applied to the normal-metal terminal controls the occupation of Andreev energy levels En , and therefore controls the Josephson current flowing through these levels. Whenever the probe voltage crosses an Andreev level, the Josep...
متن کاملJosephson current and multiple Andreev reflections in graphene SNS junctions
The Josephson effect and superconducting proximity effect were observed in superconductor-graphenesuperconductor SGS Josephson junctions with coherence lengths comparable to the distance between the superconducting leads. By comparing the measured gate dependence of the proximity induced subgap features multiple Andreev reflections and of the supercurrent to theoretical predictions, we find tha...
