Weyl points in multiterminal hybrid superconductor-semiconductor nanowire devices
E. V. Repin, Yuli V. Nazarov
Abstract
The technology of superconductor-semiconductor nanowire devices has matured in the last years in the course of Majorana research. This makes it feasible to design more complex and sophisticated devices. The authors investigate multiterminal superconductor-semiconductor wires to probe the feasibility of another topological phenomenon, namely, Weyl singularities in their Andreev spectrum. They discover an abundance of Weyl singularities for devices with intermediate spacing between the electrodes.
