Generalized Second Law of Thermodynamics in Extended Theories of Gravity
M. Akbar
By employing the general expression of temperature associated with the apparent horizon of…
Ricci Solitons and Einstein-Scalar Field Theory
M M Akbar, E Woolgar
B List has recently studied a geometric flow whose fixed points correspond to static Ricci flat spacetimes. It is now known that this flow is in fact Ricci flow modulo pullback by…
Viscous Cosmology and Thermodynamics of Apparent Horizon
M. Akbar
It is shown that the differential form of Friedmann equations of FRW universe can be recast as a similar form of the first law, , of thermodynamics at the a…
Thermodynamic Interpretation of Field Equations at Horizon of BTZ Black Hole
M. Akbar
A spacetime horizon comprising with a black hole singularity acts like a boundary of a thermal system associated with the notions of temperature and entropy. In case of static metr…
Thermodynamic Behavior of Friedmann Equation at Apparent Horizon of FRW Universe
M. Akbar, Rong-Gen Cai
It is shown that the differential form of Friedmann equation of a FRW universe can be rewritten as a universal form at apparent horizon, where and are the…
Friedmann Equations of FRW Universe in Scalar-tensor Gravity, f(R) Gravity and First Law of Thermodynamics
M. Akbar, Rong-Gen Cai
In the paper, hep-th/0501055 (R.G. Cai and S.P. Kim, JHEP {\bf 0502}, 050 (2005)), it is shown that by applying the first law of thermodynamics to the apparent horizon of an FRW un…
