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 THERMODYNAMICS OF LATTICE QCD [PDF]

open access: greenThe Origin of Mass and Strong Coupling Gauge Theories, 2008
Lattice QCD allows us to simulate QCD at non-zero temperature and/or densities. Such equilibrium thermodynamics calculations are relevant to the physics of relativistic heavy-ion collisions. I give a brief review of the field with emphasis on our work.

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.

Thermodynamic equilibrium in general relativity [PDF]

open access: yesPhysical Review D, 2019
The thermodynamic equilibrium condition for a static self-gravitating fluid in the Einstein theory is defined by the Tolman-Ehrenfest temperature law, $T{\sqrt {g_{00}(x^{i})}} = constant$, according to which the proper temperature depends explicitly on the position within the medium through the metric coefficient $g_{00}(x^{i})$.

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.

Open-Circuit Voltage Comes from Non-Equilibrium Thermodynamics

open access: yes, 2020
Originally derived by Walther Nernst more than a century ago, the Nernst equation for the open-circuit voltage is a cornerstone in the analysis of electrochemical systems.

Unified Extended Irreversible Thermodynamics and the Stability of Relativistic Theories for Dissipation

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In a relativistic context, the main purpose of Extended Irreversible Thermodynamics (EIT) is to generalize the principles of non-equilibrium thermodynamics to the domain of fluid dynamics.

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.

On the Thermodynamic Equilibrium in the Universe [PDF]

open access: yesProceedings of the National Academy of Sciences, 1928
With the establishing of the second law it was realized that all the actual processes on earth are irreversible and unidirectional in the sense of this law. The same is true for the solar system as the sun is radiating energy continually in an irreversible way.

Thermodynamic Efficiency Out of Equilibrium [PDF]

open access: yesBiophysical Journal, 2010
Equilibrium thermodynamics satisfactorily explains the efficiency of macroscopic machines, whose operation is posited as a quasi-static, infinite time, zero power process exemplified by the Carnot heat engine. Microscopic biomolecular motors differ markedly from their macroscopic counterparts, as they are subject to large fluctuations, operate far from
