Exact solution for scalar field collapse.
We give an exact spherically symmetric solution for the Einstein-scalar field system. The solution may be interpreted as an inhomogeneous dynamical scalar field cosmology. The spacetime has a timelike conformal Killing vector field and is asymptotically conformally flat. It also has black or white hole-like regions containing trapped surfaces. We describe the properties of the apparent horizon ...
متن کاملExact black hole solution with a minimally coupled scalar field
An exact four-dimensional black hole solution of gravity with a minimally coupled self-interacting scalar field is reported. The event horizon is a surface of negative constant curvature enclosing the curvature singularity at the origin, and the scalar field is regular everywhere outside the origin. This solution is an asymptotically locally AdS spacetime. The strong energy condition is satisfi...
متن کاملExact Conformal Scalar Field Cosmologies ∗
New exact solutions of Einstein’s gravity coupled to a self-interacting conformal scalar field are derived in this work. Our approach extends a solution-generating technique originally introduced by Bekenstein for massless conformal scalar fields. Solutions are obtained for a FriedmannRobertson-Walker geometry both for the cases of zero and non-zero curvatures, and a variety of interesting feat...
متن کاملPhases of massive scalar field collapse
We study critical behavior in the collapse of massive spherically symmetric scalar fields. We observe two distinct types of phase transition at the threshold of black hole formation. Type II phase transitions occur when the radial extent (λ) of the initial pulse is less than the Compton wavelength (μ) of the scalar field. The critical solution is that found by Choptuik in the collapse of massle...
متن کاملUnderstanding critical collapse of a scalar field
I construct a spherically symmetric solution for a massless real scalar field minimally coupled to general relativity which is discretely self-similar (DSS) and regular. This solution coincides with the intermediate attractor found by Choptuik in critical gravitational collapse. The echoing period is ∆ = 3.4453 ± 0.0005. The solution is continued to the future self-similarity horizon, which is ...
