Abstract
We demonstrate that in two-dimensional noncentrosymmetric s-wave superconductors under applied magnetic fields for a particular electron density, topological order emerges, and there exists a zero-energy Majorana fermion mode in a vortex core, which obeys non-Abelian statistics, in analogy with px+ipy superconductors, the Moore–Read Pfaffian quantum Hall state, and the gapped non-Abelian spin liquid phase of the Kitaev model.
