Entropy Principle and Recent Results in Non-Equilibrium Theories

Entropy, 2014
We present the state of the art on the modern mathematical methods of exploiting the entropy principle in thermomechanics of continuous media. A survey of recent results and conceptual discussions of this topic in some well-known non-equilibrium theories

A Schroedinger link between non-equilibrium thermodynamics and Fisher information

, 2002
It is known that equilibrium thermodynamics can be deduced from a constrained Fisher information extemizing process. We show here that, more generally, both non-equilibrium and equilibrium thermodynamics can be obtained from such a Fisher treatment ...

Thermodynamics of cosmological horizons in $f(T)$ gravity

, 2011
We explore thermodynamics of the apparent horizon in $f(T)$ gravity with both equilibrium and non-equilibrium descriptions. We find the same dual equilibrium/non-equilibrium formulation for $f(T)$ as for $f(R)$ gravity.

Entropy and Entropy Production in Multiscale Dynamics

, 2018
Heat conduction is investigated on three levels: equilibrium, Fourier, and Cattaneo. The Fourier level is either the point of departure for investigating the approach to equilibrium or the final stage in the investigation of the approach from the ...

Thermodynamics in $f(R)$ gravity in the Palatini formalism

, 2010
We investigate thermodynamics of the apparent horizon in $f(R)$ gravity in the Palatini formalism with non-equilibrium and equilibrium descriptions. We demonstrate that it is more transparent to understand the horizon entropy in the equilibrium framework

Entropy production and fluctuation theorems for active matter [PDF]

, 2017
Active biological systems reside far from equilibrium, dissipating heat even in their steady state, thus requiring an extension of conventional equilibrium thermodynamics and statistical mechanics.

Thermal boundary resistance in semiconductors by non-equilibrium thermodynamics

, 2016
We critically address the problem of predicting the thermal boundary resistance at the interface between two semiconductors by atomistic simulations. After reviewing the available models, lattice dynamics calculations and molecular dynamics simulation ...

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.

Synthesis of Equilibrium and Non-Equilibrium Thermodynamics

International Journal of Thermodynamics, 2021
The possibility of synthesis of equilibrium and non-equilibrium thermodynamics (thermostatics and thermokinetics) on classical principles as a deductive and phenomenological theory has been substantiated. This is achieved in the article on the basis of the law of conservation of energy due to its expression through the flows of the energy carrier and ...

Non-equilibrium thermodynamics of gravitational screens [PDF]

, 2014
We study the Einstein gravity equations projected on a timelike surface, which represents the time evolution of what we call a gravitational screen. We show that such a screen behaves like a viscous bubble with a surface tension and an internal energy ...
