Schwarzschild black hole perturbed by a force-free magnetic field
Haidar Sheikhahmadi
We envisage a black hole perturbed by a force-free magnetic field (FFMF) outside and attempt to determine its structure. We suppose the metric that describes this black hole is of…
On the origin of the holographic universe
Haidar Sheikhahmadi
In this work, we reexamine the holographic dark energy concept proposed already for cosmological applications. By considering, more precisely, the bounds on the entropy arising fro…
Thermodynamic geometry of static and rotating regular black holes in conformal massive gravity
Saheb Soroushfar, Reza Saffari, Amare Abebe +1
A version of massive gravity, namely conformal massive gravity, is employed to study the behavior of thermodynamic geometry for both the static and the rotating regular black holes…
Warm inflation with non-comoving scalar field and radiation fluid
Tiberiu Harko, Haidar Sheikhahmadi
We consider a warm inflationary scenario in which the two dominant matter components present in the early Universe, the scalar field, and the radiation fluid, evolve with different…
