A Geometrical Model for the Evolution of Spherical Planetary Nebulae Based on Thin-Shell Formalism
S. Danial Forghani, Ibrahim Gullu, S. Habib Mazharimousavi
A spherical planetary nebula is described as a geometric model. The nebula itself is considered as a thin-shell which visualized as a boundary of two spacetimes. The inner and oute…
Black Holes in Double-Logarithmic Nonlinear Electrodynamics
Ibrahim Gullu, S. Habib Mazharimousavi
The electric and magnetic black hole solutions are found by coupling the recently introduced nonlinear electrodynamics (NED) model, called "double logharitmic nonlinear electrodyna…
Double-logarithmic nonlinear electrodynamics
Ibrahim Gullu, S. Habib Mazharimousavi
A new model of nonlinear electrodynamics named as \emph{"double-logarithmic"} is introduced and investigated. The theory carries one dimensionful parameter of the as Born-Infel…
Spin-Spin Interactions in Massive Gravity and Higher Derivative Gravity Theories
Ibrahim Gullu, Bayram Tekin
We show that, in the weak field limit, at large separations, in sharp contrast to General Relativity (GR), all massive gravity theories predict distance-dependent spin alignments f…
Massive Higher Derivative Gravity Theories
Ibrahim Gullu
In this thesis massive higher derivative gravity theories are analyzed in some detail. One-particle scattering amplitude between two covariantly conserved sources mediated by a gra…
