Yukawa modification of Traversable Wormholes supported by Holographic Dark Energy
Remo Garattini, Phongpichit Channuie, Kirill Zatrimaylov
Inspired by holographic dark energy models, we extend the analysis performed in Ref.\cite{RGPC} taking into account Yukawa deformations on the different energy density (HDE) profil…
Polytropic wormholes
Remo Garattini, Emmanuel N. Saridakis, Athanasios G. Tzikas
Traversable wormholes in general relativity require non-standard matter sources, making the identification of physically motivated equations of state particularly important. We inv…

Remo Garattini, Francisco S. N. Lobo, Kirill Zatrimaylov
We investigate spherically symmetric and static traversable wormholes supported by exotic matter, focusing on solutions sourced by physically motivated dark matter energy density p…

Remo Garattini, Athanasios G. Tzikas
We investigate the conditions under which a rotating traversable wormhole can be supported by a Casimir source in the presence of an external electric field. Extending previous stu…
Short-range approximation to Casimir wormholes inspired by scalar and electric fields
Remo Garattini, Athanasios G. Tzikas
We investigate a static traversable wormhole sustained by a combination of a minimally coupled scalar field and an electric field, with exotic matter sourced by Casimir energy. Con…
Rotating Casimir Wormholes
Remo Garattini, Athanasios G. Tzikas
A Casimir Wormhole is a Traversable Wormhole powered by a Casimir energy source within a static reference frame. A natural extension of this system is the inclusion of rotation. We…

Remo Garattini, Kirill Zatrimaylov
Generalizing the result of H. Ellis who embedded a warp bubble in the background of a black hole, we introduce a warp bubble in a de Sitter universe. We show that under certain con…

In this contribution we explore the consequences of including additional sources to the original Casimir energy Stress-Energy Tensor. In particular, we will discuss the effects of…
Black Holes, Warp Drives, and Energy Conditions
Remo Garattini, Kirill Zatrimaylov
Following the work of H. Ellis, we study warp drives in the gravitational field of a Schwarzschild black hole. We find that as long as the warp drive crosses the black hole horizon…
Hot Casimir Wormholes
Remo Garattini, Mir Faizal
In this paper, we have for the first time considered the consequences of thermal fluctuations to the Casimir effect on a traversable wormhole. This was done by using finite tempera…
On the Wormhole--Warp Drive Correspondence
R. Garattini, K. Zatrimaylov
We propose a correspondence between the Morris--Thorne wormhole metric and a warp drive metric, which generalizes an earlier result by H. Ellis regarding the Schwarzschild black ho…
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.…

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…

Emmanuel N. Saridakis, Ruth Lazkoz, Vincenzo Salzano +50
General Relativity and the CDM framework are currently the standard lore and constitute the concordance paradigm. Nevertheless, long-standing open theoretical issues, as well as…

Remo Garattini, Piero Nicolini
The evaluation of Casimir energies in curved background spacetimes is an essential ingredient to study the stability of traversable wormholes. In practice one has to calculate the…
