Black hole thermodynamics in the Sharma-Mittal generalized entropy formalism
S. Ghaffari, H. Moradpour, A. H. Ziaie +3
Using the Sharma-Mittal entropy, we study some properties of the Schwarzschild and Schwarzschild-de Sitter black holes. The results are compared with those obtained by attributing…

Tsallis Holographic Dark Energy
M. Tavayef, A. Sheykhi, Kazuharu Bamba +1
Employing the modified entropy-area relation suggested by Tsallis and Cirto \cite{non3}, and the holographic hypothesis, a new holographic dark energy (HDE) model is proposed. Cons…

Revisiting Holographic Dark Energy in Cyclic Cosmology
A. Sheykhi, M. Tavayef, H. Moradpour
Considering the holographic dark energy (HDE) with two different Infrared (IR) cutoffs, we study the evolution of a cyclic universe which avoids the Big-Rip singularity. Our result…
