我们证明了在特定电子密度的二维非中心对称s波超导体中，在外加磁场作用下，拓扑有序出现，涡旋核中存在零能量马约兰纳费米子模式，该模式遵循非阿贝尔统计，类似于p(x)+ip(y)超导体，摩尔-里德普法芬量子霍尔态和基塔耶夫模型的间隙非阿贝尔自旋液相。
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 p(x)+ip(y) superconductors, the Moore-Read Pfaffian quantum Hall state, and the gapped non-Abelian spin liquid phase of the Kitaev model.
