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 ...

Generalized second law of thermodynamics in warped DGP braneworld [PDF]

Mod.Phys. Lett.A25:1199-1210,2010, 2008
We investigate the validity of the generalized second law of thermodynamics on the $(n-1)$-dimensional brane embedded in the $(n+1)$-dimensional bulk. We examine the evolution of the apparent horizon entropy extracted through relation between gravitational equation and the first law of thermodynamics together with the matter field entropy inside the ...

Clustering of Galaxies with Dynamical Dark Energy

, 2017
In this paper, we study thermodynamics of the cluster of galaxies under the effect of dynamical dark energy. We evaluate the configurational integral for interacting system of galaxies in an expanding universe by including the effects produced by the ...

Entropy? Honest!

Entropy, 2016
Here we deconstruct, and then in a reasoned way reconstruct, the concept of “entropy of a system”, paying particular attention to where the randomness may be coming from. We start with the core concept of entropy as a count associated with a description;

Minimal Length Effect on Thermodynamics and Weak Cosmic Censorship Conjecture in Anti-de Sitter Black Holes via Charged Particle Absorption

Advances in High Energy Physics, 2020
In this paper, we investigate the minimal length effects on the thermodynamics and weak cosmic censorship conjecture in a RN-AdS black hole via charged particle absorption.

Holographic Bound From Second Law of Thermodynamics

, 2000
A necessary condition for the validity of the holographic principle is the holographic bound: the entropy of a system is bounded from above by a quarter of the area of a circumscribing surface measured in Planck areas.

Interacting Three Fluid System and Thermodynamics of the Universe Bounded by the Event Horizon [PDF]

, 2010
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 in nature and interaction between then is assumed.

The two parts of the second law of thermodynamics

Revista Brasileira de Ensino de Física
According to Sommerfeld, the well known Clausius and Kelvin statements of the second law of thermodynamics comprises two parts. The first part includes the Carnot principle that all Carnot engines operating between the same temperatures have the same ...

Second law of information dynamics

AIP Advances, 2022
One of the most powerful laws in physics is the second law of thermodynamics, which states that the entropy of any system remains constant or increases over time.
