In the infrared limit the N-particle ground-state wavefunctions of the bulk happen to be exactly equal to the N-point space-time correlation functions for certain topological superconductors. We explain this (1), beginning with the p+ip state in D=2+1. We write Z(J), the generating function for wavefunctions, as a path Euclidean integral. Varying the chemical potential as a function of Euclidean time between weak and strong pairing states is shown to extract the wavefunction. Upon a Euclidean rotation that exchanges time and space, approximate Lorentz invariance converts the system to one with a spatial edge and Z(J) to the generator of spacetime correlation functions for the edge fields. We also provide a D=3+1 example, superfluid 3 He- B, and a p- wave superfluid in D=1+1. Our method works only when particle number is not conserved, as in superconductors. 1 Life at the edge The boundaries or edges of condensed matter systems re- ceived scant attention until recent developments showed them to be fertile areas of research both in the Fractional Quantum Hall E ect (FQHE) (1-3). and in topological in- sulators and superconductors (4,5,7,6,8-10). These works established that in certain topological insulators (which in- cludes superconductors because they are gapped in the bulk) the edges or boundaries carry gapless excitations which are unusual. The edge modes are saved from acquiring a gap due to various impurities because of the underlying topo- logical quantum number. The edge modes in a d 1 dimen- sional boundary of a bulk system in d dimensions cannot exist in generic d 1 dimensional systems that were not boundaries. For example the edge state at the d = 2 sur- face of a certain d = 3 insulator is described at low ener- gies by a single Dirac cone, while a generic d = 2 system
