Nonequilibrium thermodynamics in cavity optomechanics

open access: yesFundamental Research, 2023
Classical thermodynamics has been a great achievement in dealing with systems that are in equilibrium or near equilibrium. As an emerging field, nonequilibrium thermodynamics provides a general framework for understanding the nonequilibrium processes ...

Thermodynamics “beyond” local equilibrium [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
Nonequilibrium thermodynamics has shown its applicability in a wide variety of different situations pertaining to fields such as physics, chemistry, biology, and engineering. As successful as it is, however, its current formulation considers only systems close to equilibrium, those satisfying the so-called local equilibrium hypothesis.

Linear stochastic thermodynamics

open access: yesNew Journal of Physics, 2022
We study the thermodynamics of open systems weakly driven out-of-equilibrium by nonconservative and time-dependent forces using the linear regime of stochastic thermodynamics. We make use of conservation laws to identify the potential and nonconservative

Thermodynamics of scale-dependent Friedmann equations

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this work, the role of a time-varying Newton constant under the scale-dependent approach is investigated in the thermodynamics of the Friedman equations.

Multiscale Thermodynamics

open access: yesEntropy, 2021
Multiscale thermodynamics is a theory of the relations among the levels of investigation of complex systems. It includes the classical equilibrium thermodynamics as a special case, but it is applicable to both static and time evolving processes in ...

Equilibrium and transient thermodynamics: A unified dissipaton-space approach. [PDF]

open access: yesJournal of Chemical Physics, 2020
This work presents a unified dissipaton-equation-of-motion (DEOM) theory and its evaluations on the Helmholtz free energy change due to the isotherm mixing of two isolated subsystems.

On universal features of the turbulent cascade in terms of non-equilibrium thermodynamics [PDF]

open access: yesJournal of Fluid Mechanics, 2017
Features of the turbulent cascade are investigated for various datasets from three different turbulent flows, namely free jets as well as wake flows of a regular grid and a cylinder.

Entropy and the Second Law of Thermodynamics—The Nonequilibrium Perspective

open access: yesEntropy, 2020
An alternative to the Carnot-Clausius approach for introducing entropy and the second law of thermodynamics is outlined that establishes entropy as a nonequilibrium property from the onset.

Modeling the transformation of І and ІІІ types kerogen by the method of entropy maximization

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2021
Purpose, methods and research methodology. The aim of the work is to calculate and compare the trends of transformation of organic matter of I-A and III-A type kerogen, which is in contact with organic and inorganic gases in the process of immersion of ...
