Thermodynamics of Quasi-Topological Cosmology [PDF]
, 2013 In this paper, we study thermodynamical properties of the apparent horizon in a universe governed by quasi-topological gravity. Our aim is twofold.

Thermodynamics in f(R,T) Theory of Gravity
, 2012 A non-equilibrium picture of thermodynamics is discussed at the apparent horizon of FRW universe in $f(R,T)$ gravity, where $R$ is the Ricci scalar and $T$ is the trace of the energy-momentum tensor.

Generalized Second Law of Thermodynamics for Non-canonical Scalar Field Model with Corrected-Entropy [PDF]
, 2015 In this work, we have considered a non-canonical scalar field dark energy model in the framework of flat FRW background. It has also been assumed that the dark matter sector interacts with the non-canonical dark energy sector through some interaction ...

Thermodynamical aspects of modified holographic dark energy model
, 2014 We investigate the unified first law and the generalized second law in a modified holographic dark energy model. The thermodynamical analysis on the apparent horizon can work and the corresponding entropy formula is extracted from the systematic ...

On Thermodynamics Problems in the Single-Phase-Lagging Heat Conduction Model
Entropy, 2016 Thermodynamics problems for the single-phase-lagging (SPL) model have not been much studied. In this paper, the violation of the second law of thermodynamics by the SPL model is studied from two perspectives, which are the negative entropy production ...

Thermodynamics of Lemaitre-Tolman-Bondi Model
, 2010 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 is calculated and is found to coincide with the apparent horizon.

The generalized second law of thermodynamics with Barrow entropy
European Physical Journal C: Particles and Fields, 2021 We investigate the validity of the generalized second law of thermodynamics, applying Barrow entropy for the horizon entropy. The former arises from the fact that the black-hole surface may be deformed due to quantum-gravitational effects, quantified by ...
