Manipulation of Vortices to control the Chiral Andreev Edge States*

At the interface between a superconductor and a quantum Hall (QH) region, the QH edge states are proximitized to form the chiral Andreev edge states (CAES). We have previously shown that the interference of CAES is highly sensitive to the configuration of the vortices in the superconductor. By modifying the design of the superconducting electrode, we can manipulate the configuration of vortices, which allows us to both explore the properties of the CAES and to use the non-local CAES interference as an effective probe of the vortex configuration. The study and control of the vortices and the CAES are an important step in the development of chiral superconducting devices.
