Quantum time dilation in the near-horizon region of a black hole
H. Hadi, K. Atazadeh, F. Darabi
In this work, we obtain a relation for average quantum time dilation between two clocks A and B in the near-horizon region of a black hole supported by the Rindler metric and confo…
Time evolution of the inside of the black hole's horizon
H. Hadi, F. Darabi
We consider the Wheeler-DeWitt equation near the horizon of the black hole where the entangled vacuum state is chosen as the static universe state. Then, using the entangled proper…
Quantum time in near-horizon region of a black hole
H. Hadi, F. Darabi, K. Atazadeh
The understanding of time and dynamics can be elucidated by examining the concept of entanglement in quantum theory. This particular perspective on time is referred to as the timel…
D-bound and Bekenstein bound for McVittie solution surrounded by dark energy cosmological fields
H. Hadi, Y. Heydarzade, F. Darabi +1
The cosmological candidate fields for dark energy as quintessence, phantom and cosmological constant, are studied in terms of an entropic hypothesis imposed on the McVittie solutio…
Entropic considerations on the Universe and Universe-Black Hole Systems
H. Hadi, F. Darabi, Y. Heydarzade
We study the entropic considerations on the Universe system and the Universe-Black hole system, filled by cosmological constant or exotic quintessence-like and phantom-like fields…
D-bound and Bekenstein Bound for the Surrounded Vaidya Black Hole
H. Hadi, F. Darabi, K. Atazadeh +1
We study the Vaidya black hole surrounded by the exotic quintessence-like, phantom-like and cosmological constant-like fields by means of entropic considerations. Explicitly, we sh…
Braneworld Black Holes and Entropy Bounds
Y. Heydarzade, H. Hadi, C. Corda +1
The Bousso's D-bound entropy for the various possible black hole solutions on a 4-dimensional brane is checked. It is found that the D-bound entropy here is apparently different fr…
Bousso's Covariant Entropy Bound and Padmanabhan's Emergent Universe
H. Hadi, Y. Heydarzade, F. Darabi
We study the Padmanabhan's emergent Universe in the context of Bousso's covariant entropy conjecture. We find that for a flat Universe, this conjecture can be applied for the syste…
Emergent Cosmos in Einstein-Cartan Theory
H. Hadi, Y. Heydarzade, M. Hashemi +1
Based on the Padmanabhan's proposal, the accelerated expansion of the universe can be driven by the difference between the surface and bulk degrees of freedom in a region of space,…
Emergent Universe in the Braneworld Scenario
Y. Heydarzade, H. Hadi, F. Darabi +1
According to Padmanabhan's proposal, the difference between the surface degrees of freedom and the bulk degrees of freedom in a region of space may result in the acceleration of Un…
