Dynamics and instability of false vacuum bubbles
Abstract
This paper examines the classical dynamics of falsevacuum regions embedded in surrounding regions of true vacuum, in the thinwall limit. The dynamics of all generally relativistically allowed solutionsmost but not all of which have been previously studiedare derived, enumerated, and interpreted. We comment on the relation of these solutions to possible mechanisms whereby inflating regions may be spawned from noninflating ones. We then calculate the dynamics of firstorder deviations from spherical symmetry, finding that many solutions are unstable to such aspherical perturbations. The parameter space in which the perturbations on bound solutions inevitably become nonlinear is mapped. This instability has consequences for the FarhiGuthGuven mechanism for baby universe production via quantum tunneling.

It is pointed out that there is no reason to believe that detachment of the false vacuum is ever achieved for nondegenerate real vacua in view of the instability of nondegenerate Killing horizons to the past of their bifurcation.

Dynamics of falsevacuum bubbles
The possibility of localized inflation is investigated by calculating the dynamics of a spherically symmetric region of false vacuum which is separated by a domain wall from an infinite region of true vacuum. For a range of initial conditions, the falsevacuum region will undergo inflation. An observer in the exterior truevacuum region will describe the system as a black hole, while an observer in the interior will describe a closed universe which completely disconnects from the original spacetime. We suggest that this mechanism is likely to lead to an instability of Minkowski space: a region of space might undergo amore » 
Dynamics of false vacuum bubbles with nonminimal coupling
We study the dynamics of false vacuum bubbles. A nonminimally coupled scalar field gives rise to the effect of negative tension. The mass of a false vacuum bubble from an outside observer's point of view can be positive, zero, or negative. The interior false vacuum has de Sitter geometry, while the exterior true vacuum background can have geometry depending on the vacuum energy. We show that there exist expanding false vacuum bubbles without the initial singularity in the past. 
Dynamics of false vacuum bubbles in BransDicke theory
We study the dynamics of false vacuum bubbles in the BransDicke theory of gravity by using the thin shell or thin wall approximation. We consider a false vacuum bubble that has a different value for the BransDicke field between the inside false vacuum region and the outside true vacuum region. Within a certain limit of field values, the difference of field values makes the effective tension of the shell negative. This allows new expanding false vacuum bubbles to be seen by the outside observer, which are disallowed in Einstein gravity. 
Quantum nucleation of falsevacuum bubbles
We show that a small bubble of false vacuum can tunnel to the critical size for inflation, and calculate the amplitude in leading WKB approximation. An initially nonsingular space becomes an exterior space plus a baby universe (which contains the bubble), joined by a blackhole singularity. We work in a Hamiltonian formalism; the corresponding Euclidean bounce is shown to have a degenerate vierbein.
