Equilibrium thermodynamics in modified gravitational theories

, 2010
We show that it is possible to obtain a picture of equilibrium thermodynamics on the apparent horizon in the expanding cosmological background for a wide class of modified gravity theories with the Lagrangian density $f(R, \phi, X)$, where $R$ is the ...

Sorption Thermodynamics of CO₂, H₂O, and CH₃OH in a Glassy Polyetherimide: A Molecular Perspective

Membranes, 2019
In this paper, the sorption thermodynamics of low-molecular-weight penetrants in a glassy polyetherimide, endowed with specific interactions, is addressed by combining an experimental approach based on vibrational spectroscopy with thermodynamics ...

Non-equilibrium Thermodynamics of Spacetime

, 2006
It has previously been shown that the Einstein equation can be derived from the requirement that the Clausius relation dS = dQ/T hold for all local acceleration horizons through each spacetime point, where dS is one quarter the horizon area change in ...

The equilibrium of neural firing: A mathematical theory

AIP Advances, 2014
Inspired by statistical thermodynamics, we presume that neuron system has equilibrium condition with respect to neural firing. We show that, even with dynamically changeable neural connections, it is inevitable for neural firing to evolve to equilibrium.

Thermodynamics and Fluctuations Far From Equilibrium

Entropy, 2010
We review a coherent mesoscopic presentation of thermodynamics and fluctuations far from and near equilibrium, applicable to chemical reactions, energy transfer and transport processes, and electrochemical systems.

Local Temperature of Out-of-Equilibrium Quantum Electron Systems

, 2013
We show how the local temperature of out-of-equilibrium, quantum electron systems can be consistently defined with the help of an external voltage and temperature probe. We determine sufficient conditions under which the temperature measured by the probe

Strong coupling thermodynamics and stochastic thermodynamics from the unifying perspective of time-scale separation

Physical Review Research, 2022
Assuming time-scale separation, a simple and unified theory of thermodynamics and stochastic thermodynamics is constructed for small classical systems strongly interacting with their environments in a controllable fashion.

Experiments in Stochastic Thermodynamics: Short History and Perspectives

Physical Review X, 2017
We summarize in this article the experiments which have been performed to test the theoretical findings in stochastic thermodynamics such as fluctuation theorem, Jarzynski equality, stochastic entropy, out-of-equilibrium fluctuation dissipation theorem ...

Relativistic non-equilibrium thermodynamics revisited

, 2005
Relativistic irreversible thermodynamics is reformulated following the conventional approach proposed by Meixner in the non-relativistic case. Clear separation between mechanical and non-mechanical energy fluxes is made.

Multiscale modeling of electrolytes in porous electrode: From equilibrium structure to non-equilibrium transport

Green Energy & Environment, 2020
Understanding the mechanisms and properties of various transport processes in the electrolyte, porous electrode, and at the interface between electrode and electrolyte plays a crucial role in guiding the improvement of electrolytes, materials and ...
