Sung-Won Kim, Hyunjoo Lee
TL;DR
This paper derives exact solutions for charged traversable wormholes considering backreaction effects of scalar fields and electric charge, analyzing stability conditions based on the shape function properties.
Contribution
It provides the first exact solutions for charged wormholes including backreaction effects of scalar and electric charges, extending previous static models.
Findings
Charged wormholes can be stable under certain shape function conditions.
Backreaction effects of scalar and electric charges are incorporated into exact solutions.
Stability criteria depend on the positiveness and flareness of the shape function.
Abstract
In this paper, the backreaction to the traversable Lorentzian wormhole spacetime by the scalar field or electric charge is considered to find the exact solutions. The charges play the role of the additional matter to the static wormhole which is already constructed by the exotic matter. The stability conditions for the wormhole with scalar field and electric charge are found from the positiveness and flareness for the wormhole shape function.
