Topology Change by Quantum Tunneling in (2+1)-Dimensional Einstein Gravity : Invited Papers

概要
- 論文の詳細を見る
We investigate possibilities of topology change and nucleation of universes in the (2+1)-dimensional Einstein gravity model with negative cosmological constant. We demonstrate that topology change and nucleation phenomena can occur by quantum tunneling by explicitly constructing Euclidean signature hyperbolic 3-geometry. The amplitude is explicitly calculated in the WKB approximation. Point particles can be accommodated in this scheme as topological defects in space-time. They are pair created and annihilated when the universe changes its topology.
