Hawking radiation as tunnelling from the trapping horizon of a general non-static spherically symmetric space-time
Subenoy Chakraborty, Nairwita Mazumder, Ritabrata Biswas
Using tunnelling approach, Hawking radiation is derived for a general class of non-static spherically symmetric space time. The standard tunnelling rate formula is obtained using t…
The generalized second law of thermodynamics and the nature of the Entropy Function
Subenoy Chakraborty, Nairwita Mazumder, Ritabrata Biswas
In black hole physics, the second law of thermodynamics is generally valid whether the black hole is a static or a non-static one. Considering the universe as a thermodynamical sys…
Interacting Three Fluid System and Thermodynamics of the Universe Bounded by the Event Horizon
Nairwita Mazumder, Ritabrata Biswas, Subenoy Chakraborty
The work deals with the thermodynamics of the universe bounded by the event horizon. The matter in the universe has three constituents namely dark energy, dark matter and radiation…
Thermodynamics of Lemaitre-Tolman-Bondi Model
Subenoy Chakraborty, Nairwita Mazumder, Ritabrata Biswas
Here we consider our universe as inhomogeneous spherically symmetric Lemaitre-Tolman-Bondi Model and analyze the thermodynamics of this model of the universe. The trapping horizon…
Unified First Law and Some Comments
Subenoy Chakraborty, Ritabrata Biswas, Nairwita Mazumder
In this small article, unified first law has been analyzed and some results have been deduced from it. The results have been presented in the form of lemmas and some conclusions ha…
Cosmological Evolution Across Phantom Crossing and the Nature of the Horizon
Subenoy Chakraborty, Nairwita Mazumder, Ritabrata Biswas
In standard cosmology, with the evolution of the universe, the matter density and thermodynamic pressure gradually decreases. Also in course of evolution, the matter in the univers…
