Gravitational Collapse in Repulsive Gravity
Mohsen Fathi, Morteza Mohseni
In this paper we work out collapsing conditions for a spherical star in the weak field limit of the gravity and discuss the importance of the parameter to generate di…
Evolving Horava Cosmological Horizons
Mohsen Fathi, Morteza Mohseni
Several sets of radially propagating null congruence generators are exploited in order to form 3-dimensional marginally trapped surfaces, referred to as black hole and cosmological…
Massive Gravitons on Bohmian Congruences
Mohsen Fathi, Morteza Mohseni
Taking a quantum corrected form of Raychaudhuri equation in a geometric background described by a Lorentz-violating massive theory of gravity, we go through investigating a time-li…
Focusing of world-lines in Weyl gravity
Morteza Mohseni, Mohsen Fathi
We study the evolution of time-like congruences in the vacuum solutions of Weyl conformal theory of gravity. Using the Raycaudhuri equation, we show that for positive values of the…
Cartographic distortions make dielectric spacetime analog models imperfect mimickers
Mohsen Fathi, Robert T. Thompson
It is commonly assumed that if the optical metric of a dielectric medium is identical to the metric of a vacuum space-time then light propagation through the dielectric mimics ligh…
