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…
Accretion of Holographic Dark Energy : Dependency only upon Horizon Radius of Expanding Universe
Ritabrata Biswas, Nairwita Mazumder, Subenoy Chakraborty
In this paper we deal with accretion of dark energy in the holographic dark energy model for a general non-rotating static spherically symmetric black hole. The mass of the black h…
Generalized Second Law of Thermodynamics on the Event Horizon for Interacting Dark Energy
Nairwita Mazumder, Subenoy Chakraborty
Here we are trying to find the conditions for the validity of the generalized second law of thermodynamics (GSLT) assuming the first law of thermodynamics on the event horizon in b…
Scalar-Tensor Theory of Gravity and Generalized Second Law of Thermodynamics on the Event Horizon
Nairwita Mazumder, Subenoy Chakraborty
In blackhole physics, the second law of thermodynamics is generally valid whether the blackhole is a static or a non-static one. Considering the universe as a thermodynamical syste…
The generalized second law of thermodynamics of the universe bounded by the event horizon and modified gravity theories
Nairwita Mazumder, Subenoy Chakraborty
In this paper, we investigate the validity of the generalized second law of thermodynamics of the universe bounded by the event horizon. Here we consider homogeneous and isotropic…
Validity of the Generalized Second Law of Thermodynamics of the Universe Bounded by the Event Horizon in Holographic Dark Energy Model
Nairwita Mazumder, Subenoy Chakraborty
In this letter, we investigate the validity of the generalized second law of thermodynamics of the universe bounded by the event horizon in the holographic dark energy model. The u…
Validity of the Generalized Second Law of Thermodynamics of the Universe Bounded by the Event Horizon in Brane Scenario
Nairwita Mazumder, Subenoy Chakraborty
In this paper, we examine the validity of the generalized second law of thermodynamics (GSLT) of the universe bounded by the event horizon in brane-world gravity. Here we consider…
FRW Universe in Horava Gravity
Nairwita Mazumder, Subenoy Chakraborty
Recently, a field theoretic model for a UV complete theory of gravity has been proposed by Horava. This theory is a non-relativistic renormalizable gravity theory which coincides w…
