Majorana corner modes from magnetic textures on superconductors

This paper proposes a new way to generate Majorana corner modes, which are promising for quantum computing applications, using a layered structure with a quantum spin Hall insulator between a superconductor and a noncollinear magnetic texture. The magnetic texture induces effective spin-orbit coupling and Zeeman fields to stabilize the higher order topological superconducting phase with Majorana corner modes.
