p波超导体亚能隙区的有效场论
Effective Field Theory for a p-wave Superconductor in the Subgap Regime
摘要：
我们构造了一个二维无脊椎p波成对超导体的有效场论，它忠实地描述了体态的拓扑性质，并为涡旋核和边缘的亚能隙态提供了一个模型.特别是它捕获拓扑保护的零模式，并具有正确的基态退化的环面。我们还表明，我们的有效场论成为一个拓扑场论在一个定义良好的标度极限和旋涡具有预期的非阿贝尔编织统计。
英文摘要：
We construct an effective field theory for the 2d spineless p-wave paired superconductor that faithfully describes the topological properties of the bulk state, and also provides a model for the subgap states at vortex cores and edges. In particular it captures the topologically protected zero modes and has the correct ground state degeneracy on the torus. We also show that our effective field theory becomes a topological field theory in a well defined scaling limit and that the vortices have the expected non-abelian braiding statistics.
