Abstract:

We study the dynamics of a spherically symmetric dust shell separating two spacetime domains, the interior one being a part of the de Sitter spacetime and the exterior one having the extremal Reißner-Nordström geometry. Extending the ideas of previous works on the subject, we show that the it is possible to determine the (metastable) WKB quantum states of this gravitational system.
