A toy model for slowly growing wormholes as effective topology changes
Samuel L. Braunstein
Abstract
We present a toy model for growing wormholes as a model of effective low-energy topology changes. We study the propagation of quantum fields on a 1+1 spacetime analogous to the trouser-leg topology change. A low-energy effective topology change is produced by a physical model which corresponds to a barrier smoothly changing the tunneling probability between two spatial regions.
