Thermodynamic analysis of modified teleparallel gravity involving higher-order torsion derivative terms

European Physical Journal C: Particles and Fields, 2019
The present study is elaborated to investigate the validity of thermodynamical laws in a modified teleparallel gravity based on higher-order derivative terms of torsion scalar.

Cosmological and thermodynamics analysis in Weyl gravity

European Physical Journal C: Particles and Fields, 2020
In the framework of modified Weyl gravity, we observe the equilibrium picture of the thermodynamical laws for flat Friedmann–Robertson–Walker metric with chameleon scalar field and analyze the validity of the generalized second law of thermodynamics and ...

First order and stable relativistic dissipative hydrodynamics

, 2012
Relativistic thermodynamics is derived from kinetic equilibrium in a general frame. Based on a novel interpretation of Lagrange multipliers in the equilibrium state we obtain a generic stable but first order relativistic dissipative hydrodynamics ...

Open system trajectories specify fluctuating work but not heat

, 2016
Based on the explicit knowledge of a Hamiltonian of mean force, the classical statistical mechanics and equilibrium thermodynamics of open systems in contact with a thermal environment at arbitrary interaction strength can be formulated.

Entropy correction and phase transition of n-dimensional charged dilaton dS black holes

European Physical Journal C: Particles and Fields
The manifest disparity in Hawking radiation temperatures between black hole and cosmological horizons in de Sitter (dS) spacetime reveals a non-equilibrium thermal configuration, inherently violating thermodynamic stability criteria. This asymmetry poses

New formulation of local-equilibrium thermodynamics

AIP Advances, 2019
This study points out that the conventional separation of balance equations for energy in fluids into a flow and a source term is not thermodynamically valid.

Thermal Contact

Entropy, 2008
The concepts of temperature and entropy as applied in equilibrium thermodynamics do not easily generalize to nonequilibrium systems and there are transient systems where thermodynamics cannot apply.

The Rayleigh-Brillouin Spectrum in Special Relativistic Hydrodynamics

, 2009
In this paper we calculate the Rayleigh-Brillouin spectrum for a relativistic simple fluid according to three different versions available for a relativistic approach to non-equilibrium thermodynamics.

Why so many "Schools" of Thermodynamics?

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
A classification representing some main branches of phenomenological non-equilibrium thermodynamics is discussed. Differences and similarities of these selected branches are explained.
