Dynamics of Yang-Mills Cosmology Bubbles in Bartnik-McKinnon Spacetimes
Shuxue Ding
We investigate the dynamics of a Yang-Mills cosmology (YMC, the FRW type spacetime) bubble in the Bartnik-McKinnon (BK) spacetimes. Because a BK spacetime can be identified to a YM…
Four Dimensional Quantum Topology Changes of Spacetimes
Shuxue Ding, Yasushige Maeda, Masaru Siino
We investigate topology changing processes in the WKB approximation of four dimensional quantum cosmology with a negative cosmological constant. As Riemannian manifolds which descr…
Topology Changes by Quantum Tunneling in Four Dimensions
Ding Shuxue, Yasushige Maeda, Masaru Siino
We investigate topology-changing processes in 4-dimensional quantum gravity with a negative cosmological constant. By playing the ``gluing-polytope game" in hyperbolic geometry, we…
Cosmological Sphaleron from Real Tunneling and Its Fate
Shuxue Ding
We show that the cosmological sphaleron of Einstein-Yang-Mills system can be produced from real tunneling geometries. The sphaleron will tend to roll down to the vacuum or pure gau…
