Galactic Halo Wormhole Solutions in f(T) Gravity

Advances in High Energy Physics, 2014
The proposal of galactic halo region is based on the idea that dark halos contain some characteristics needed to support traversable wormhole solutions. We explore wormhole solutions in this region in the framework of generalized teleparallel gravity. We

Strings on AdS wormholes

Journal of Physics: Conference Series, 2009
We consider the behavior of open strings on AdS wormholes in Gauss-Bonnet theory, which are the Gauss-Bonnet gravity duals of a pair of field theories. A string with both endpoints on the same side of the wormhole describes two charges within the same field theory, which exhibit Coulomb interaction for small separation.

Shadow and strong gravitational lensing of new wormhole solutions supported by embedding Class-I condition

European Physical Journal C: Particles and Fields
This study deals with the new class of embedded wormhole solutions in the background of general relativity. Two newly calculated wormhole solutions satisfy all the required properties.

Charged wormhole solutions in 4D Einstein-Gauss-Bonnet gravity

Nuclear Physics B
In the present work, we construct models of static wormholes in 4-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity with an (an)isotropic energy momentum tensor (EMT) and a Maxwell field as supporting matters for the wormhole geometry assuming a ...

Probing the geometries of wormholes: A comparative study of f(R,T) and f(Q,T) theories in the presence of BEC matter

Nuclear Physics B
This study explores wormhole solutions within two distinct modified gravity theories, namely f(R,T) gravity and f(Q,T) gravity, incorporating Bose-Einstein condensate (BEC) dark matter to analyze their geometric properties.

Are slowly rotating Ellis-Bronnikov wormholes stable?

Physics Letters B
We investigate the radial perturbations of Ellis-Bronnikov wormholes (l=0) in a slowly rotating background expanded up to second order in rotation. We find indications that simple wormhole solutions such as Ellis-Bronnikov in General Relativity can be ...

Impact of charge on traversable wormhole solutions and modified f(R, ϕ) gravity

Nuclear Physics B
In this paper, we investigate the traversable wormhole solutions in the presence of charge within the framework of f(R, ϕ) gravity, where R represents the Ricci scalar and ϕ denotes the scalar potential, respectively.

Generalized Finslerian Wormhole Models in $f(\mathcal{R},\mathcal{T})$ Gravity

Particles
This article explores wormhole solutions within the framework of Finsler geometry and the modified gravity theory. Modifications in gravitational theories, such as f(R,T) gravity, propose alternatives that potentially avoid the exotic requirements.
