TL;DR
This paper explores classical scalar fields coupled to gravity in a brane-world scenario, presenting wormhole solutions for different brane geometries with implications for higher-dimensional models.
Contribution
It introduces new wormhole solutions in a brane-world context with scalar fields and dynamic extra dimensions.
Findings
Found a Tolman wormhole solution for R x S^3 brane with Lorentz metric.
Derived a wormhole solution for R x AdS_3 brane with positive definite metric.
Analyzed scalar field effects in a rolling fifth radius scenario.
Abstract
Two classical scalar fields are minimally coupled to gravity in the Kachru-Shulz-Silverstein scenario with a rolling fifth radius. A Tolman wormhole solution is found for a R x S^3 brane with Lorentz metric and for a R x AdS_3 brane with positive definite metric.
