Hybrid topological platforms (C03)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277101999

Project C03 will study hybrid platforms which have been much investigated in recent years in the context of topological superconductivity. We will explore novel phenomena in such platforms, including semiconductor-superconductor hybrid wires as well as magnetic adatoms on superconductors. Work on semiconductor-superconductor systems will focus on developing tripartite wires including epitaxial ferromagnets as well a new generation of Josephson junction arrays. Work on magnetic adatoms on superconductors will explore two-dimensional arrays of adatoms built by manipulation with a scanning tunneling microscope tip. This will be complemented by studies of fractional Chern insulators, which may hold much promise when forming hybrids with superconductors.
