Geodesically complete cyclic cosmologies and entropy
Petar Pavlović, Marko Sossich
We demonstrate that there exists a class of cyclic cosmological models, such that these models can in principle solve the problem of the entropy growth, and are at the same time ge…
Creation of wormholes during the cosmological bounce
Petar Pavlović, Marko Sossich
In this work we demonstrate that wormholes can in principle be naturally created during the cosmological bounce without the need for the exotic matter or any kind of additional mod…
On spherically symmetric vacuum solutions and horizons in covariant gravity theory
Andrew DeBenedictis, Saša Ilijić, Marko Sossich
In this paper we study properties that the vacuum must possess in the minimal extension to the teleparallel equivalent of general relativity (TEGR) where the action is supplemented…
Cosmological bounce and the cosmological constant problem
Petar Pavlović, Marko Sossich
We discuss how the modifications of the standard Einstein's equations needed to support the cosmological bounce can at the same time lead to vanishing of the well known cosmologica…
Dynamic properties of cyclic cosmologies
Petar Pavlović, Marko Sossich
Our first goal in this work is to study general and model-independent properties of cyclic cosmologies. The large number of studies of bouncing cosmologies and different cyclic sce…
Boson stars in extended theory of gravity
Saša Ilijić, Marko Sossich
Spherically symmetric configurations of the non-interacting massive complex scalar field, representing non-rotating boson stars, are considered within the framework of the modified…
Influence of the Vacuum Polarization Effect on the Motion of Charged Particles in the Magnetic Field around a Schwarzschild Black Hole
Petar Pavlović, Andrey Saveliev, Marko Sossich
The consequences of the vacuum polarization effect in magnetic fields around a Schwarzschild Black Hole on the motion of charged particles are investigated in this work. Using the…
The effect of vacuum polarization on the magnetic fields around a Schwarzschild black hole
Petar Pavlović, Marko Sossich
It is a well known result that the effect of vacuum polarization in gravitational fields will lead to a non-minimal coupling between gravity and electromagnetism. We investigate th…
Compact stars in extended theory of gravity
Sasa Ilijic, Marko Sossich
We consider static spherically symmetric self-gravitating configurations of the perfect fluid within the framework of the torsion-based extended theory of gravity. In particular, w…
The Effects of Running Gravitational Coupling On Rotating Black Holes
Sumarna Haroon, Mubasher Jamil, Kai Lin +3
In this work we investigate the consequences of running gravitational coupling on the properties of rotating black holes. Apart from the changes induced in the space-time structure…
Cyclic cosmology in modified gravity
Petar Pavlovic, Marko Sossich
In this work we propose a new general model of eternal cyclic Universe. We start from the assumption that quantum gravity corrections can be effectively accounted by the addition o…
Cosmological wormholes in theories of gravity
Sebastian Bahamonde, Mubasher Jamil, Petar Pavlovic +1
Motivated by recent proposals of possible wormhole existence in galactic halos, we analyse the cosmological evolution of wormhole solutions in modified gravity. We construct…
Wormholes in viable modified theories of gravity and Weak Energy Condition
Petar Pavlović, Marko Sossich
In this work wormholes in viable gravity models are analysed. We are interested in exact solutions for stress-energy tensor components depending on different shape and redsh…
