Topological Black Holes in Lovelock-Born-Infeld Gravity
M. H. Dehghani, N. Alinejadi, S. H. Hendi
In this paper, we present topological black holes of third order Lovelock gravity in the presence of cosmological constant and nonlinear electromagnetic Born-Infeld field. Dependin…
Taub-NUT Black Holes in Third order Lovelock Gravity
S. H. Hendi, M. H. Dehghani
We consider the existence of Taub-NUT solutions in third order Lovelock gravity with cosmological constant, and obtain the general form of these solutions in eight dimensions. We f…
Magnetic Strings in Einstein-Born-Infeld-Dilaton Gravity
M. H. Dehghani, A. Sheykhi, S. H. Hendi
A class of spinning magnetic string in 4-dimensional Einstein-dilaton gravity with Liouville type potential which produces a longitudinal nonlinear electromagnetic field is present…
String inspired explanation for the super-acceleration of our universe
Ahmad Sheykhi, Bin Wang, Nematollah Riazi
We investigate the effect of the bulk content in the general Gauss-Bonnet braneworld on the evolution of the universe. We find that the Gauss-Bonnet term and the combination of the…
Boundary Conditions in Stepwise Sine-Gordon Equation and Multi-Soliton Solutions
N. Riazi, A. Sheykhi
We study the stepwise sine-Gordon equation, in which the system parameter is different for positive and negative values of the scalar field. By applying appropriate boundary condit…
Deep Connection Between Thermodynamics and Gravity in Gauss-Bonnet Braneworld
Ahmad Sheykhi, Bin Wang, Rong-Gen Cai
We disclose the deep connection between the thermodynamics and gravity in a general braneworld model with curvature correction terms on the brane and in the bulk, respectively. We…
