(Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 2012)We consider Einstein-Maxwell-Dilaton (EMD) Lagrangian supplemented by double Liouville potentials to enrich our system and investigate the resulting dynamics. The general solution provides us alternative structures induced ...
-
(Astrophysics and Space Science, Springer, 2014)We study quasinormal modes (QNMs) of uncharged Grumiller black hole (GBH). This massive BH has a Rindler acceleration a, and hence it is also called Rindler modified Schwarzschild BH. After reducing the radial equation of ...
-
(Springer, 2009-01)Non-Hermitian but PϕTϕ-symmetrized spherically-separable Dirac and Schrödinger Hamiltonians are considered. It is observed that the descendant Hamiltonians Hr , Hθ , and Hϕ play essential roles and offer some “user-feriendly” ...
-
(Physics Letters B, Elsevier, 2012)We employ the 'square root' of the Maxwell Lagrangian (i.e. \surd(F_{{\mu}{\nu}}F^{{\mu}{\nu}})), coupled with gravity to search for the possible linear potentials which are believed to play role in confinement. It is found ...
-
(Physical Review D, American Physical Society (APS), 2014)We revisit the stability analysis of cylindrical thin shell wormholes which have been studied in literature so far. Our approach is more systematic and in parallel to the method which is used in spherically symmetric thin ...
-
(Physical Review D, American Physical Society (APS), 2010)Recently in (Phys. Rev. D 76, 087502 (2007) and Phys. Rev. D 77, 089903(E) (2008)) a thin-shell wormhole has been introduced in 5-dimensional Einstein-Maxwell-Gauss-Bonnet (EMGB) gravity which was supported by normal matter. ...
-
(Astrophysics and Space Science, Springer, 2013)A regular class of static, cylindrically symmetric pure magnetic field metrics is rederived in a different metric ansatz in all dimensions. Radial, time dependent perturbations show that for dimensions d>3 such spacetimes ...
-
(Physical Review D, American Physical Society (APS), 2013)We study the stability of thin-shell wormholes in Einstein-Maxwell-Gauss-Bonnet gravity. The equation of state of the thin shell wormhole is considered first to obey a generalized Chaplygin gas and then we generalize it ...
-
(Journal of Mathematical Physics, American Institute of Physics (AIP), 1988)Some properties of the space-times admitting two spacelike Killing vectors are studied. In particular, using harmonic maps the degree of freedom on the M' manifold is exploited to add scalar and electromagnetic fields ...
-
(SIGMA, 2010)A new class of non-Hermitian Hamiltonians with real spectrum, which are written as a real linear combination of su(2) generators in the form H=ωJ3+αJ−+βJ+, α≠β, is analyzed. The metrics which allows the transition to the ...
-
(Classical and Quantum Gravity, Institution of Physics (IOP) Publishing, 1997)Sandwich waves in the Einstein–Maxwell theory are expressed globally by introducing step functions at the boundaries. We show that a test particle crossing such a wave zone extracts energy from the sandwich wave.
-
(Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 2010)We present a theorem in d-dimensional static, spherically symmetric spacetime in generic Lovelock gravity coupled with a non-linear electrodynamic source to generate solutions. The theorem states that irrespective of the ...
-
(The European Physical Journal C, Springer, 2014-03-13)We revisit the regular black hole found by Hayward in 4 -dimensional static, spherically symmetric spacetime. To find a possible source for such a spacetime we resort to the nonlinear electrodynamics in general relativity. ...
-
(The European Physical Journal C, Springer, 2014)The Zipoy-Voorhees-Weyl (ZVW) spacetime characterized by mass (M) and oblateness (δ) is proposed in the construction of viable thin-shell wormholes (TSWs). Departure from spherical / cylindrical symmetry yields positive ...
-
(European Physical Journal C, Springer, 2015)Real-valued triplet of scalar fields as source gives rise to a metric which tilts the scalar, not the light cone, in 2+1-dimensions. The topological metric is static, regular and it is characterized by an integer κ=±1,±2,.... ...
-
(Springer, 2016-06-02)We study the quantum tunneling of charged massive vector bosons from a charged static and a rotating black string. We apply the standard methods, first we use the WKB approximation and the Hamilton-Jacobi equation, and ...
-
(THE EUROPEAN PHYSICAL JOURNAL PLUS, Springer, 2015-06-11)In this article, we consider the Hawking radiation (HR) of vector (massive spin-1) particles from the traversable Lorentzian wormholes (TLWH) in 3+1 dimensions. We start by providing the Proca equations for the TLWH. ...
-
(Physical Review D, American Physical Society (APS), 2013)We present a solution for the Einstein-Maxwell (EM) equations which unifies both the magnetic Bertotti-Robinson (BR) and Melvin (ML) solutions as a single metric in the axially symmetric coordinates t,ρ,z,φ. Depending on ...
-
(EPL, IOP Publishing (Institute of Physics), 2015-04-24)We show in detail that the Parikh-Wilczek tunneling method (PWTM), which was designed for resolving the information loss problem in Hawking radiation (HR) fails whenever the radiation occurs from an isothermal process. ...
-
(AMER PHYSICAL SOC, 1999)Tunneling problems are characterized by different quantum time scales of motion. In this paper, we identify a tunneling time scale, which is based on a simple variational principle. The method utilizes the stationary e ...
