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…
Traversable Wormholes induced by polytropic energy density
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…
Macroscopic "Lola/Mola" Cat State
Harman Deep Kaur, Mariagrazia Trapanese, Kirill Zatrimaylov
We present the first--ever example of a macroscopic system in a quantum superposition. The system in question is a Siamese cat known as Lola; however, on a time scale of about 12 h…
Warp Drive in a De Sitter Universe
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…
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…
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…
Dark Matter, Rotation Curves, and the Morphology of Galaxies
Kirill Zatrimaylov
In this thesis, we investigate some aspects of dark matter phenomenology and its predictive power in explaining the flattening of galaxy rotation curves at large distances. After o…
On Filaments, Prolate Halos and Rotation Curves
K. Zatrimaylov
We propose a simple geometrical mechanism for the flattening of galactic rotation curves, the local compression of field lines around their planes induced either by the presence of…
A Critique of Covariant Emergent Gravity
K. Zatrimaylov
I address some problems encountered in the formulation of relativistic models encompassing the MOND phenomenology of radial acceleration. I explore scalar and vector theories with…
