Complexified von Roos Hamiltonian's η-weak-pseudo-Hermiticity, isospectrality and exact solvability (IOP Publishing, 2008)A complexified von Roos Hamiltonian is considered and a Hermitian first-order intertwining differential operator is used to obtain the related position-dependent mass η-weak-pseudo-Hermitian Hamiltonians. Using a ...

(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 ...
-
(International Journal of Theoretical Physics, Springer, 2003)A scalar field generalization of Xanthopoulos's cylindrically symmetric solutions of the vacuum Einstein equation is obtained. The obtained solution preserves the properties of the Xanthopoulos solution, which are regular ...
-
(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 ...
-
(Nuovo Cimento B, Springer, 1988)Using Einstein-Rosen's linearly polarized waves as the seed solution, we derive an interesting solution for the Einstein's equations that describes the evolution of such waves with the second polarization.
-
(IOP Science, 2006-08-02)The d-dimensional generalization of the point canonical transformation for a quantum particle endowed with a position-dependent mass in the Schr¨odinger equation is described. Illustrative examples including the harmonic ...
-
(Physics Letters A, Elsevier, 2011)Thin-shell wormholes in Einstein-Yang-Mills-dilaton (EYMD) gravity are considered. We show that a non-asymptotically flat (NAF) black hole solution of the d-dimensional EYMD theory provides stable thin-shell wormholes which ...
-
(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 ...
-
(IOP Publishing, 2003)The observation that the existence of the amazing reality and discreteness of the spectrum need not necessarily be attributed to the Hermiticity of the Hamiltonian is re-emphasized in the context of the non-Hermitian Dirac ...
-
(Physical Review D, American Physical Society (APS), 1988)We present a new family of exact solutions for the Einstein equations that describes colliding gravitational shock waves with cross polarization. In the limit of single polarization it reduces to a family that, up to a ...
-
(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 ...
-
(International Journal of Modern Physics A, World Scientific Publishing, 2009)The Cauchy horizon forming colliding wave solution due to Chandrasekhar and Xanthopoulos (CX) has been generalized by inclusion of the NUT (Newman - Unti - Tamburino) parameter. This is done by transforming the part of the ...
-
(Physical Review D, American Physical Society (APS), 2001)A single pulse of null dust and colliding null dust both transform a regular horizon into a spacelike singularity in the space of colliding waves. The local isometry between such space-times and black holes extrapolates ...
-
(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 ...
-
(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, ...
