标题： Equality of bulk wave functions and edge correlations in topological superconductors: A spacetime derivation

摘要： 对于某些系统，体内的N粒子基态波函数恰好等于边缘处的N点时空关联函数，在红外极限下。我们展示为什么对于一类拓扑超导体来说这必须成立，从D=2+1中的p+ip态开始。显示通过在弱配对和强配对态之间变化化学势作为欧几里得时间的函数可以提取波函数。然后，一个交换时间和空间的欧几里得旋转和近似的洛伦兹不变性导致边缘连接。我们说明了向其他维度（例如D=3+1中的3He-B相）以及类似分数量子化拓扑超导体的关联态的直接扩展。 显示英文摘要

摘要： For certain systems, the N-particle ground-state wavefunctions of the bulk happen to be exactly equal to the N-point space-time correlation functions at the edge, in the infrared limit. We show why this had to be so for a class of topological superconductors, beginning with the p+ip state in D=2+1. Varying the chemical potential as a function of Euclidean time between weak and strong pairing states is shown to extract the wavefunction. Then a Euclidean rotation that exchanges time and space and approximate Lorentz invariance lead to the edge connection. We illustrate straightforward extension to other dimensions (eg. 3He- B phase in D=3+1) and to correlated states like fractionalized topological superconductors.
