Tsallis holographic dark energy in the brane cosmology
S. Ghaffari, H. Moradpour, J. P. Morais Graça +2
We study some cosmological features of Tsallis holographic dark energy (THDE) in Cyclic, DGP and RS II braneworlds. In our setup, a flat FRW universe is considered filled by a pres…
Energy definition and dark energy: a thermodynamic analysis
H. Moradpour, J. P. Morais Graça, I. P. Lobo +1
Accepting the Komar mass definition of a source with energy-momentum tensor , and using the thermodynamic pressure definition, we find a relaxed energy-momentum conservatio…
Effects of a string cloud on the criticality and efficiency of AdS black holes as heat engines
J. P. Morais Graça, Iarley P. Lobo, Valdir B. Bezerra +1
We study the black hole thermodynamics in the presence of a string cloud matter distribution, considering a work term due to a variable cosmological "constant" in arbitrary dimensi…
Thermodynamic approach to holographic dark energy and the Rényi entropy
H. Moradpour, S. A. Moosavi, I. P. Lobo +3
Using the first law of thermodynamics, we propose a relation between the system entropy () and its IR () and UV () cutoffs. In addition, applying this relation to the appa…
Generalized entropy formalism and a new holographic dark energy model
A. Sayahian Jahromi, S. A. Moosavi, H. Moradpour +4
Recently, the Rényi and Tsallis generalized entropies have extensively been used in order to study various cosmological and gravitational setups. Here, using a special type of gene…
