We explore the thermodynamics of dark energy taking into account the existence of the
observer's event horizon in accelerated universes. Except for the initial stage of Chaplygin …

Recently proposed extensions of target-space duality and Narain transformations can be
used to generate highly non-trivial conformal string backgrounds out of (almost) trivial ones …

We investigate the validity the generalized second law of thermodynamics in a general
braneworld model with curvature correction terms on the brane and in the bulk, respectively …

We investigate the generalized second law of thermodynamics (GSL) in generalized
theories of gravity. We examine the total entropy evolution with time including the horizon …

We have investigated the thermodynamical properties of the Universe with dark energy.
Adopting the usual assumption in deriving the constant co-moving entropy density that the …

In this work we have investigated the effects of three nongaussian entropies, namely, the
modified Rényi entropy (MRE), the Sharma-Mittal entropy (SME) and the dual Kaniadakis …

In the framework of Saez–Ballester (SB) theory, the current study proposes a reconstruction
scheme for Tsallis and Kaniadakis holographic dark energy, particular cases of a more …

Our Universe has an arrow of time. In accordance with the second law of thermodynamics,
entropy has been increasing ever since the big bang. The fact that matter is in thermal …
