Black Holes and Warp Drive
Remo Garattini, Kirill Zatrimaylov
We study the generalizations of the original Alcubierre warp drive metric to the case of curved spacetime background. We find that the presence of a horizon is essential when one m…
Traversable Wormholes induced by Stress Energy Conservation: combining Casimir Energy with a scalar field
R. Garattini, A. G. Tzikas
We investigate possible manifolds characterizing traversable wormholes in the presence of a scalar field minimally coupled to gravity, which has both kinetic and potential energy.…
Traversable Wormholes supported by Holographic Dark Energy with a modified Equation of State
Remo Garattini, Phongpichit Channuie
Inspired by holographic dark energy models, we consider different energy density profiles as possible sources needed to have traversable wormholes solutions. Since such energy dens…
Effects of an Electric Charge on Casimir Wormholes: Changing the Throat Size
Remo Garattini
In this paper we continue the investigation about the connection between Casimir energy and the traversability of a wormhole. In addition to the negative energy density obtained by…
