(Physical Review D, Springer, 2011)We obtain a class of magnetically charged solutions in 2+1 dimensional Einstein - Power - Maxwell theory. In the linear Maxwell limit, such horizonless solutions are known to exist. We show that in 3D geometry, black hole ...
-
(The European Physical Journal C, Springer, 2015)We revisit the shapes of the throats of wormholes, including thin-shell wormholes (TSWs) in 2+1−dimensions. In particular, in the case of TSWs this is done in a flat 2+1−dimensional bulk spacetime by using the standard ...
-
(Physical Review D, American Physical Society, 2015)We present a class of exact solutions in the framework of (2+1)-dimensional Einstein gravity coupled minimally to a doublet of scalar fields. Our solution can be interpreted upon the tuning of parameters as an asymptotically ...
-
(Astroparticle Physics, Elsevier, 2016)We analytically study the scalar perturbation of non-asymptotically flat (NAF) rotating linear dilaton black holes (RLDBHs) in 4-dimensions. We show that both radial and angular wave equations can be solved in terms of the ...
-
(Physical Review D, American Physical Society (APS), 2011)It is shown that in the static, spherically symmetric spacetime the problem of metric f(R) gravity coupled with non-linear Yang-Mills (YM) field constructed from the Wu-Yang ansatz as source, can be solved in all dimensions. ...
-
(European Physical Journal C, Springer, 2013)We consider a particular Bardeen black hole in 2+1-dimensions. The black hole is sourced by a radial electric field in non-linear electrodynamics (NED). The solution is obtained anew by the alternative Hamiltonian formalism. ...
-
(Physical Review D, American Physical Society (APS), 2012)We consider the interesting ‘‘near-horizon test’’ reported in S. E. P. Bergliaffa and Y. E. C. de O. Nunes,Phys. Rev. D 84, 084006 (2011) for any static, spherically symmetric black hole solution admitted in f(R)gravity. ...
-
(European Physical Journal C, Springer, 2011)We consider the particular class of f(R) gravities minimally coupled with Yang - Mills (YM) field in which the Ricci scalar =R_{0}= constant in all dimensions d\geq4. Even in this restricted class the spacetime has unlimited ...
-
(The European Physical Journal C, Springer, 2014)The role of angular momentum in a 2+1-dimensional rotating thin-shell wormhole (TSW) is considered. Particular emphasis is made on stability when the shells (rings) are counterrotating. We find that counter-rotating halves ...
-
(International Journal of Theoretical Physics, Springer, 2011)We show in detail that the entropic force of the static spherically symmetric spacetimes with unusual asymptotics can be calculated through the Verlinde's arguments. We introduce three different holographic screen candidates, ...
-
(Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 2010)We give a general class of static, spherically symmetric, non-asymptotically flat and asymptotically non-(anti) de Sitter black hole solutions in Einstein-Maxwell-Dilaton (EMD) theory of gravity in 4-dimensions. In this ...
-
(Physical Review D, American Physical Society (APS), 2010)We investigate the dynamics of a d-dimensional domain wall (DW) in a d+1-dimensional Einstein-Gauss-Bonnet (EGB) bulk. Exact effective potential induced by the Gauss-Bonnet (GB) term on the wall is derived. In the absence ...
-
(European Physical Journal C, Springer, 2013)We find Einstein-Yang-Mills (EYM) black hole solutions endowed with massless scalar hair in the presence of a potential V(ϕ) as function of the scalar field ϕ. Choosing V(ϕ)=constant (or zero) sets the scalar field to ...
-
(Physics Letters B, Elsevier, 2009)We show in detail that the Hawking temperature calculated from the surface gravity is in agreement with the result of exact semi-classical radiation spectrum for higher dimensional linear dilaton black holes in various ...
-
(Astrophysics and Space Science, Springer, 2012)This paper deals with the semiclassical radiation spectrum of static and circularly symmetric 3D charged dilaton black holes with cosmological constant {\Lambda} in non-asymptotically flat spacetimes. We first review the ...
-
(Journal of Experimental and Theoretical Physics (JETP), Springer, 2013)Hawking radiation of a non-asymptotically flat (NAF) 4-dimensional spherically symmetric and static dilatonic black hole (BH) via the Hamilton-Jacobi (HJ) method has been studied. In addition to the naive coordinates, we ...
-
(Modern Physics Letters A, World Scientific Publishing, 2015)We present black hole solutions in 2+1−dimensional Einstein's theory of gravity coupled with Born-Infeld nonlinear electrodynamic and a massless self-interacting scalar field. The model has five free parameters: mass M, ...
-
(The European Physical Journal Plus, Springer, 2015)We consider Einstein-Maxwell-self-interacting scalar field theory described by a potential V(ϕ) in 2+1−dimensions. The self-interaction potential is chosen to be a highly non-linear double-Liouville type. Exact solutions, ...
-
(Journal of Cosmology and Astroparticle Physics, Institute of Physics Publishing (IOP), 2014)In this study we advocate the view that the cosmological constant is of electromagnetic (em) origin, which can be generated from the collision of em shock waves coupled with gravitational shock waves. The wave profiles ...
-
(International Journal of Theoretical Physics, Springer, 2011)It has been shown recently that information is lost in the Hawking radiation of the linear dilaton black holes in various theories when applying the tunneling formulism without considering quantum gravity effects. In this ...
