Cylindrical wormholes in DGP gravity
(American Physical Society, 2013-03)
We construct traversable thin-shell wormholes in the Dvali-Gabadadze-Porrati theory with cylindrical symmetry applying the cut and paste procedure to a flat black string solution of the fivedimensional vacuum Einstein field ...
Wormholes in Einstein-Born-Infeld theory
(American Physical Society, 2009-11)
Spherically symmetric thin-shell wormholes are studied within the framework of Einstein-Born-Infeld theory. We analyze the exotic matter content, and find that for certain values of the Born-Infeld parameter the amount of ...
More about thin-shell wormholes associated to cosmic strings
(American Physical Society, 2009-06)
Previous analysis about thin-shell wormholes associated to cosmic strings are extended. More evidence is found supporting the conjecture that, under reasonable assumptions about the equations of state of matter on the ...
Traversable wormholes in five-dimensional Lovelock theory
(American Physical Society, 2019-08-08)
In general relativity, traversable wormholes are possible provided they do not represent shortcuts in the spacetime. Einstein equations, together with the achronal averaged null energy condition, demand to take longer for ...
Some general aspects of thin-shell wormholes with cylindrical symmetry
(American Physical Society, 2010-04)
In this article we study a general class of nonrotating thin-shell wormholes with cylindrical symmetry. We consider two physically sound definitions of the flare-out condition and we show that the less restrictive one ...
Erratum: Some general aspects of thin-shell wormholes with cylindrical symmetry
(American Physical Society, 2014-10)
Erratum: [Phys. Rev. D 81, 084022 (2010)]
Asymptotically anti-de Sitter cylindrical thin-shell wormholes
(American Physical Society, 2015-03)
In this article we investigate cylindrical thin-shell wormholes which are asymptotically anti-de Sitter. We analyze their stability under perturbations preserving the symmetry by using two different methods. We compare ...
Traversable wormhole magnetic monopoles from Dymnikova metric
(Springer, 2019-11)
We study a traversable wormhole originated by a transformation over the 4D Dymnikova metric, which describes analytic black holes (BH). By using a transformation of coordinates which is adapted from the one used in the ...
Probing global aspects of a geometry by the self-force on a charge: Spherical thin-shell wormholes
(American Physical Society, 2013-12-15)
The self-interaction for a static point charge in the space-time of a thin-shell wormhole constructed connecting two identical Schwarzschild geometries is calculated in a series expansion. The electrostatic self-force is ...
Thin-shell wormholes in Einstein–Maxwell theory with a Gauss–Bonnet term
(Springer/Plenum Publishers, 2006-12)
We study five dimensional thin-shell wormholes in Einstein–Maxwell theory with a Gauss–Bonnet term. The linearized stability under radial perturbations and the amount of exotic matter are analyzed as a function of the ...
