Controlling Superconducting Topological Hinge Modes

Abstract

Long elusive in topological superconductors are smoking-gun experiments controlling the emergence of quasi-particles or probing their non-local and topologically protected properties. These are crucial to uncovering the unique topological superconducting state, using them for quantum transduction and topological quantum computing. This proposal combines the co-PIs and AFRLs unique expertise to control and probe 1D chiral hinge modes in the topological superconductor Fe(Se,Te). Via heterostructures with the topological, metallic magnet Fe3(Ge,Ga)Te2, the team will locally create 1D modes. We will uncover the non-local spin properties via spin transport and microwave excitation to measure their potential for exciting and detecting magnons toward quantum transduction.
