Asymptotic conformal symmetry at spatial infinity
Sepideh Bakhoda, Fatemeh Mahdieh, Hossein Shojaie
In this paper, the effects of adding spatial conformal symmetry to the asymptotic symmetry group of an asymptotically conformally flat spacetime are studied. It is shown that, in a…
Large Gauge Symmetries of an Asymptotically de Sitter Horizon: An Extended First Law of Thermodynamics
Fatemeh Mahdieh, Hossein Shojaie
In this paper, we show that a universe with a dynamical cosmological constant approaching pure de Sitter at timelike infinity, enjoys an infinite dimensional symmetry group at its…
Generalized Second Law of Thermodynamics with Corrected Entropy in Tachyon Cosmology
H. Farajollahi, A. Ravanpak, H. Shojaie +1
This work is to study the generalized second law (GSL) of thermodynamics in tachyon cosmology where the boundary of the universe is assumed to be enclosed by a dynamical apparent h…
A varying-c cosmology
Hossein Shojaie, Mehrdad Farhoudi
We develop a new model for the Universe based on two key assumptions: first, the inertial energy of the Universe is a constant, and second, the total energy of a particle, the iner…
