Canonical Acoustic Thin-Shell Wormholes

Jusufi, Kimet; Övgün, Ali (World Scientific Publishing Co Pte Ltd, 2017-02-16)

In this paper, we model a canonical acoustic thin-shell wormhole (CATSW) in the framework of analogue gravity systems. In this model, we apply cut and paste technique to join together two spherically symmetric, analogue ...
A particular thin-shell wormhole

Sakallı, İzzet; Övgün, Ali (Springer, 2017-02-09)

Using a black hole with scalar hair, we construct a scalar thin-shell wormhole (TSW) in 2+1 dimensions by applying the Visser cut and paste technique. The surface stress, which is concentrated at the wormhole throat, is ...
Ph.D Defense- Studies on Thin-shells and Thin-shell Wormholes

Ali, Övgün (2016-07-18)
Rotating Thin-Shell Wormhole

Övgün, Ali (SpringerLink, 2016-11-08)

We construct a rotating thin-shell wormhole using a Myers-Perry black hole in five dimensions, using the Darmois-Israel junction conditions. The stability of the wormhole is analyzed under perturbations. We find that exotic ...
Thin-shell wormholes from the regular Hayward black hole

Halilsoy, Mustafa; Övgün, Ali; Mazharimousavi, S. Habib (The European Physical Journal C, Springer, 2014-03-13)

We revisit the regular black hole found by Hayward in 4 -dimensional static, spherically symmetric spacetime. To find a possible source for such a spacetime we resort to the nonlinear electrodynamics in general relativity. ...
