Titre |
Multi-terminal Josephson junctions as topological matter |
|
Résumé |
We show that n-terminal Josephson junctions with conventional superconductors may provide a straightforward realization of tunable topological materials in n−1 dimensions, the independent superconducting phases playing the role of quasi-momenta. In particular, we find zero-energy Weyl points in the Andreev bound state spectrum of 4-terminal junctions. The topological properties of the junction may be probed experimentally by measuring the transconductance between two voltage-biased leads, which we predict to be quantized |
