Quasibound states of the Dirac field in Schwarzschild and Reissner-Nordström black hole backgrounds
Ciprian A. Sporea
In this paper, we study the existence of (quasi)bound states in two spacetime geometries describing Schwarzschild and Reissner-Nordström black holes. For obtaining this type of sta…
Scattering of quantum fields by a MOG Black Hole
Ciprian A. Sporea
This paper aims to investigate the scattering of fermions by spherically symmetric MOG black holes, which are a type of black holes encountered in scalar-tensor-vector modified gra…
Scattering of Dirac fermions by spherical massive bodies
Ion I. Cotaescu, Ciprian A. Sporea
The asymptotic form of Dirac spinors in the field of a Schwarzschild black hole is used for deriving analytically for the first time the phase shifts of the partial wave analysis o…
Fermion scattering by a class of Bardeen black holes
Ciprian A. Sporea
In this paper the scattering of fermions by a class of Bardeen black holes is investigated. After obtaining the scattering modes by solving the Dirac equation in this geometry, we…
A simple model for explaining Galaxy Rotation Curves
Aneta Wojnar, Ciprian A. Sporea, Andrzej Borowiec
A new simple expression for the circular velocity of spiral galaxies is proposed and tested against HI Nearby Galaxy Survey (THINGS) data set. Its accuracy is compared with the one…
Scattering of massless fermions by Schwarzschild and Reissner-Nordström black holes
Ciprian A. Sporea
In this paper we are studying the scattering of massless Dirac fermions by Schwarzschild and Reissner-Nordström black holes. This is done by applying the partial wave analysis to t…
