(INST PHYSICS ACAD SCI CZECH REPUBLIC, Springer (Online Publishing), 2002)Magnetic fingerprints on the spectra of an interacting electron with a negatively charged ion in a parabolic quantum dot (QD), and of two interacting electrons in such a dot, are investigated via a pseudoperturbative ...
-
(Springer, 2016-05-30)In this paper, we investigate the tunneling process of charged massive bosons W± (spin-1 particles) from noncommutative charged black holes such as charged RN black holes and charged BTZ black holes. By applying the WKB ...
-
(Physics Letters A, Elsevier, 1981)We present another method of generating new solutions from old ones in general relativity. In particular we apply the method to some well-known classes of gravitational fields.
-
(Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 1995)We present the metric of a Schwarzschild (S) black hole coupled to an external, stationary electromagnetic Bertotti–Robinson (BR) solution. This metric generalizes a previous metric that served to unify the S and BR ...
-
(European Physical Journal C: Particles and Fields, Springer, 2014)We construct thin shell wormholes in the magnetic Melvin universe. It is shown that in order to make a TSW in the Melvin spacetime the radius of the throat can not be larger than 2B0 in which B0 is the magnetic field ...
-
(Astroparticle Physics, Elsevier, 2015)The model proposed originally by Mannheim and Kazanas for fitting the shapes of galactic rotation curves has recently been considered by Grumiller to describe gravity of a central object at large distances. Herein we employ ...

(Brown University, 2009)Based on multiplicative calculus, the finite difference schemes for the numerical solution of multiplicative differential equations and Volterra differential equations are presented. Sample problems were solved using these ...
-
(General Relativity and Gravitation, Springer, 2009)We find large classes of non-asymptotically flat Einstein-Yang-Mills-Dilaton (EYMD) and Einstein-Yang-Mills-Born-Infeld-Dilaton (EYMBID) black holes in N-dimensional spherically symmetric spacetime expressed in terms of ...
-
(IOP Publishing, 2015)We suggest a new deformed Schioberg-type potential for diatomic molecules. We show that it is equivalent to Tietz-Hua oscillator potential. We discuss how to relate our deformed Schi\"oberg potential to Morse, to Deng-Fan ...
-
(European Physical Journal C: Particles and Fields, Springer, 2014)We introduce a class of solutions in 2+1−dimensional Einstein-Power-Maxwell theory for circularly symmetric electric field. The electromagnetic field is considered with an angular component given by $% F_{\mu \nu ...
-
(Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-06)ABSTRACT: Some new exact solutions in a model of f (R) gravity are obtained. Three kinds of matter fields have been used to obtain exact analytic solutions. In the first solution, the Yang-Mills fields are incorporated ...
-
(Journal of Mathematical Physics, American Institute of Physics (AIP), 1992)The quaternionic version of the Ernst formalism is used to propose an alternative generalization of the Zipoy-Voorhees metric that represents spinning spheroids. Rotating discs and their superposition that generalize the ...
-
(Physical Review D, American Physical Society (APS), 2008)We introduce new black hole solutions to the Einstein-Yang-Mills-Born-Infeld (EYMBI), Einstein-Yang-Mills-Born-Infeld-Gauss-Bonnet (EYMBIGB) and Einstein-Yang-Mills-Born-Infeld-Gauss-Bonnet-Lovelock (EYMBIGBL) gravities ...
-
(General Relativity and Gravitation, 2003)A technique is given to generate coupled scalar field solutions in colliding Einstein - Maxwell (EM) waves. By employing the Bell - Szekeres solution as seed and depending on the chosen scalar field it is possible to ...
-
(The Chemical Engineering Journal, 1987)We present a more general solution of the standard deep bed filtration equations which explains the initial improvement of effluent quality as a suspension passes through a porous medium. Our solution gives a good ...
-
(Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2020)In this work, we have used the Friedmann equation of general relativity with quantum correction terms to the Newtonian potential to obtain the modified Friedmann equation with quantum correction. The behavior of the solution ...
-
(Springer, 2006)A class of non-Hermitian d-dimensional Hamiltonians with position-dependent mass and their η-pseudo-Hermiticity generators is presented. Illustrative examples are given in 1D, 2D, and 3D for different position-dependent ...
-
(IOP Science, 2008-06)We analyze the zero energy solutions, of a two-dimensional system which undergoes a non-radial symmetric, complex potential V (r,φ). By virtue of the coherent states concept, the localized states are constructed, and the ...
-
(Eastern Mediterranean University (EMU), 2013)ABSTRACT: In the framework of the non-linear electrodynamics, we introduce a new Lagrangian with Maxwell limit which admits a regular electric field and electric potential at the origin. In static spherically symmetric ...
