Cylindrical thin-shell wormholes
Ernesto F. Eiroa, Claudio Simeone
TL;DR
This paper develops a formalism for the dynamics of non-rotating cylindrical thin-shell wormholes, analyzing their evolution based on initial conditions and specific metric forms related to cosmic strings.
Contribution
It introduces a general formalism for cylindrical thin-shell wormholes and explicitly derives their evolution, highlighting the dependence on initial velocity and metric properties.
Findings
Throat can collapse, stay static, or expand based on initial velocity.
Explicit evolution equations for cylindrical wormholes are obtained.
The behavior depends solely on initial conditions and metric form.
Abstract
A general formalism for the dynamics of non rotating cylindrical thin-shell wormholes is developed. The time evolution of the throat is explicitly obtained for thin-shell wormholes whose metric has the form associated to local cosmic strings. It is found that the throat collapses to zero radius, remains static or expands forever, depending only on the sign of its initial velocity.
