Antipodal correlation on the meron wormhole and a bang-crunch universe

Understand

We present a covariant euclidean wormhole solution to Einstein Yang-Mills system and study scalar perturbations analytically.

• The fluctuation operator has a positive definite spectrum.
• We compute the Euclidean Green's function, which displays maximal antipodal correlation on the smallest three sphere.
• Upon analytic continuation, it corresponds to the Feynman propagator on a compact bang-crunch universe.
