(Eastern Mediterranean University (EMU), 2011)According to the Eric Verlinde’s arguments on the gravity, we study the entropic force of two spacetimes without and with dilaton field, which are the Schwarzschild black hole and the charged dilaton black hole respectively. ...
-
(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 ...
-
(General Relativity and Gravitation, Springer, 1993)By considering an uncharged mass embedded in an external electromagnetic field we show that the Einstein corrections to the Newtonian results may further be modified
-
(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, ...
-
(Physics Letters, Elsevier, 2008)By employing the higher dimensional version of the Wu-Yang Ansatz we obtain black hole solutions in the spherically symmetric Einstein-Yang-Mills (EYM) theory. Although these solutions were found recently by other means, ...
-
(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 ...
-
Energy-Levels Crossing and Radial Dirac Equation: Supersymmetry and Quasi-Parity Spectral Signatures (Springer US, 2008)The (3+1)-dimensional Dirac equation with position dependent mass in 4-vector electromagnetic fields is considered. Using two over-simplified examples (the Dirac-Coulomb and Dirac-oscillator fields), we report energy-levels ...
-
(Inst Physıcs Acad Scı Czech Republıc, 2001)The energy levels of neutral atoms supported by Yukawa potential, V(r)=-Z exp(-\alpha r)/r, are studied, using both dimensional and dimensionless quantities, via a new analytical methodical proposal (devised to solve for ...

-
(Amer Chemical Soc, 2006)A survey on the attitudes of engineering faculty to chemistry, physics, and mathematics was conducted with the aim of clarifying the attitudes of engineering faculty to chemistry courses in relation to engineering education ...
-
(International Journal of Theoretical Physics, Springer, 2016)Quantum gravity has exciting peculiarities on the Planck scale.The effect of generalized uncertainty principle (GUP) to the entangled scalar/fermion particles’ tunneling from a Schwarzschild black hole immersed in an ...
-
(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 ...
-
(Physical Review D, American Physical Society (APS), 1990)We obtain the exact behavior of the cross-polarized cylindrical Einstein-Maxwell waves that generalizes the well-known Einstein-Rosen waves. In the presence of the second mode of polarization the outgoing waves interact ...
-
(American Institute of Physics, 2010)We study a quantum model with nonisotropic two-dimensional oscillator potential but with additional quadratic interaction x1x2x1x2 with imaginary coupling constant. It is shown that for a specific connection between coupling ...
-
(Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-08)In this study we consider two different and particular quantum systems. The first system is a one-dimensional particle confined within an infinite well with the left wall at rest and the right wall moving with or without ...
-
(Canadian Journal of Physics, NRC Research Press, 2009)Exact solutions of a massive complex scalar field equation in the geometry of a Garfinkle-Horowitz-Strominger (stringy) black hole with magnetic charge is explored. The separated radial and angular parts of the wave equation ...
-
(Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)ABSTRACT: We investigate the existence of Reissner-Nordström (RN) type black holes in f (R) gravity. Our emphasis is to derive, in the presence of electrostatic source, the necessary conditions which provide such static, ...

(International Journal of Modern Physics D, World Scientific Publishing, 2013)We investigate the existence of Reissner-Nordstr\"om (RN) type black holes in f(R) gravity. Our emphasis is to derive, in the presence of electrostatic source, the necessary conditions which provide such static, spherically ...

(Springer, 2016-05-27)Potentiality of the presence of traversable wormholes in the outer/inner regions of the halos of galaxies, situated on the Navarro-Frenk-White (NFW) density profile and Universal Rotation Curve (URC) dark matter models ...
