Hot Casimir wormholes

Journal of Cosmology and Astroparticle Physics
Abstract In this paper, we have for the first time considered the consequences of finite temperature contributions to a traversable wormhole. This was done by using finite temperature generalization of the Casimir effect as a source of a hot traversable wormhole.

THE WORMHOLE HAZARD

Time and Matter, 2006
To predict the outcome of (almost) any experiment we have to assume that our spacetime is globally hyperbolic. The wormholes, if they exist, cast doubt on the validity of this assumption. At the same time, no evidence has been found so far (either observational, or theoretical) that the possibility of their existence can be safely neglected.

Exploration of GUP-corrected Casimir wormholes in extended teleparallel gravity with matter coupling

Nuclear Physics B
In this manuscript, we investigate the properties of Casimir wormholes within the framework of extended teleparallel gravity, incorporating the Generalized Uncertainty Principle.

Echoes and quasi-normal modes of perturbations around Schwarzschild traversable wormholes

European Physical Journal C: Particles and Fields
We investigate the waveforms and quasi-normal modes around Schwarzschild traversable wormholes under different field perturbations, including the scalar field, the electromagnetic (vector) field, and the axial gravitational (tensor) field perturbations ...

Shadows and photon spheres in static and rotating traversable wormholes

Nuclear Physics B
We explore the shadows and photon orbits of both static and rotating traversable wormholes by employing a redshift function in combination with two distinct shape functions.

On properties of the distribution of virtual wormholes in a vacuum

European Physical Journal C: Particles and Fields
A model of spacetime foam in the form of an arbitrary distribution of spherical Euclidean wormholes is considered. A method for constructing the exact solution of Einstein’s Euclidean equations for the metric corresponding to this model is proposed.
