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…
Energy condition respecting warp drives: The role of spin in Einstein-Cartan theory
Andrew DeBenedictis, Sasa Ilijic
In this paper we study the so called "warp drive" spacetimes within the Riemann-Cartan manifolds of Einstein-Cartan theory. Specifically, the role that spin may play with r…
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…
Regular solutions in -Yang-Mills theory
Andrew DeBenedictis, Sasa Ilijic
We consider extended covariant teleparallel gravity whose action is analytic in the torsion scalar and which is sourced by an valued Yang-Mills field. Specifically…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
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…
The Spherically Symmetric Vacuum in Covariant Gravity Theory
Andrew DeBenedictis, Sasa Ilijic
Recently, a fully covariant version of the theory of torsion gravity has been introduced (arXiv:1510.08432v2 [gr-qc]). In covariant gravity the Schwarzschild solution…
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…
Note on the charged boson stars with torsion-coupled field
Dubravko Horvat, Sasa Ilijic, Anamarija Kirin +1
Within the framework of the extended teleparallel gravity, a new class of boson stars has recently been constructed by introducing the nonminimal coupling of the scalar field to th…
A novel black hole mimicker: a boson star and a global monopole nonminimally coupled to gravity
Anja Marunovic, Miljenko Murkovic
A field-theoretic model for a highly compact object that mimicks a black hole is found for the gravitationally interacting system of a boson star and a global monopole which are no…
Formation of photon spheres in boson stars with a nonminimally coupled field
Dubravko Horvat, Sasa Ilijic, Anamarija Kirin +1
A static, spherically symmetric, asymptotically flat spacetime may allow for circular, closed null-geodesics which are said to belong to a photon sphere. In the context of gravitat…
Dark energy-like stars from nonminimally coupled scalar field
Dubravko Horvat, Anja Marunovic
We show that even a rather minimal extension of the Einstein - Hilbert action by a nonminimal coupling of the scalar field to the Ricci curvature scalar results in configurations t…
On Wormhole Throats in Gravity Theory
Andrew DeBenedictis, Dubravko Horvat
We study the existence and properties of wormhole throats in modified gravity theory. Specifically, we concentrate on the cases where the lapse is not necessarily constant,…
Radial stability analysis of the continuous pressure gravastar
Dubravko Horvat, Sasa Ilijic, Anja Marunovic
Radial stability of the continuous pressure gravastar is studied using the conventional Chandrasekhar method. The equation of state for the static gravastar solutions is derived an…
Time transients in the quantum corrected Newtonian potential induced by a massless nonminimally coupled scalar field
Anja Marunovic, Tomislav Prokopec
We calculate the one loop graviton vacuum polarization induced by a massless, nonminimally coupled scalar field on Minkowski background. We make use of the Schwinger-Keldysh formal…
Gravastar Solutions with Continuous Pressures and Equation of State
A. DeBenedictis, D. Horvat, S. Ilijic +2
We study the gravitational vacuum star (gravastar) configuration as proposed by other authors in a model where the interior de Sitter spacetime segment is continuously extended to…
