A Nonsingular Brans Wormhole: An Analogue to Naked Black Holes
Nonsingular Brans Wormhole Black Holes Analogue
2011/10/10
Abstract: In a recent paper, we showed the Jordan frame vacuum Brans Class I solution provided a wormhole analogue to Horowitz-Ross naked black hole in the wormhole range -3/2<{\omega}<-4/3. Thereafte...
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
2011/10/17
Continuing work initiated in an earlier publication (Abe, ApJ, 725 (2010) 787), we study the gravitational microlensing effects of the Ellis wormhole in the weak-field limit. First, we find a suitable...
Embeddings and time evolution of the Schwarzschild wormhole
Einstein-Rosen bridge Schwarzschild wormhole embedding
2011/10/9
Abstract: We show how to embed spacelike slices of the Schwarzschild wormhole (or Einstein-Rosen bridge) in R^3. Graphical images of embeddings are given, including depictions of the dynamics of this ...
Dynamics and Thermodynamics of (2+1)-Dimensional Evolving Lorentzian Wormhole
Dynamics Thermodynamics of (2+1)-Dimensional Evolving Lorentzian Wormhole
2010/12/27
In this paper we study the relationship between the Einstein field equations for the (2+1)-dimensional evolving wormhole and the first law of thermodynamics. It has been shown that the Einstein field...
Traversable wormhole in the deformed Hořava-Lifshitz gravity
Traversable wormhole deformed Hoř ava-Lifshitz gravity
2010/12/27
Asymptotically flat wormhole solutions are found in the deformed Ho\v{r}ava-Lifshitz gravity. It turns out that higher curvature terms can not play the role of exotic matters which are crucial to form...

Wormhole Thermodynamics Entropy Horizons
2010/12/20
In this paper we study the relationship between the Einstein field
equations for the (2+1)-dimensional evolving wormhole and the first law of thermodynamics.
It has been shown that the Einstein fiel...
A comparison of Hořava-Lifshitz gravity and Einstein gravity through thin-shell wormhole construction
comparison of Hoř ava-Lifshitz gravity Einstein gravity thin-shell wormhole construction
2010/12/20
In this paper we have constructed a new class of thin-shell wormholes from black holes in Hoˇrava-Lifshitz gravity. Particular emphasis is placed on those aspects that allow a comparison of Hoˇrava-Li...
Exact wormhole solutions, while eagerly sought after, often have the appearance of being overly specialized or highly artificial. A case for the possible existence of wormholes would be more compellin...
On the Hawking wormhole horizon entropy
surface gravity spherical Rindler coordinates Holographic Principle horizons
2009/2/23
The entropy S of the horizon µ = ¼=2 of the Hawking wormhole
written in spherical Rindler coordinates is computed in this letter. Using
Padmanabhan’s prescription, we found that the s...
