Time, Irreversibility and Entropy Production in Nonequilibrium Systems
The aim of this review is to shed light on time and irreversibility, in order to link macroscopic to microscopic approaches to these complicated problems.

Progresses in generalized thermodynamic dynamic-optimization of irreversible processes
Generalized thermodynamic optimization theory is one of the research hotspots in the field of thermal science and technology. Firstly, the emergences and developments of finite time thermodynamics, entropy generation minimization, entransy theory and ...

Description of Transfer Processes in a Locally Nonequilibrium Medium
This paper presents a description of the fluctuations in transfer processes in a locally nonequilibrium medium. We obtained equations which allow the fluctuations range to be determined for a transferred physical value.

Irreversible processes without energy dissipation in an isolated Lipkin-Meshkov-Glick model. [PDF]
For a certain class of isolated quantum systems, we report the existence of irreversible processes in which the energy is not dissipated. After a closed cycle in which the initial energy distribution is fully recovered, the expectation value of a ...

Microscopic theory of irreversible processes [PDF]
The microscopic theory of irreversible processes that we developed is summarized and illustrated, using as a simple example the Friedrichs model. Our approach combines the Poincaré's point of view (dynamical interpretation of irreversibility) with the Gibbs-Einstein ensemble point of view.

From Lagrangian Mechanics to Nonequilibrium Thermodynamics: A Variational Perspective
In this paper, we survey our recent results on the variational formulation of nonequilibrium thermodynamics for the finite-dimensional case of discrete systems, as well as for the infinite-dimensional case of continuum systems.

Foundations of the Relative Constancy of Mean Velocity for Natural Streams: A General Principle of Steady State Anticipated by L. Prandtl and L. Leopold [PDF]
Mean velocity is a key parameter for understanding, modeling and predicting the complex phenomena of advection and dispersion in natural watercourses, which are threatened by human intervention and river disasters.

Energetic self-organization and development of the structural scheme of a polymer fiber tribosystem [PDF]
The article presents the results of the analysis of the main processes of friction of polymeric materials during friction with fibrous mass from the standpoint of irreversible processes and developed a block diagram of a polymer fiber tribosystem.

The rehabilitation of irreversible processes and dissipative structures’ 50th anniversary
In 2017, Ilya Prigogine would have been 100 years of age. As for any human being, this centenary is a notable event. For him, as a scientist, 2017 was also above all the 50th anniversary of dissipative structures. It was indeed in 1967 that for the first

Slow Dynamics and Thermodynamics of Open Quantum Systems
We develop a perturbation theory to estimate the finite time corrections around a quasi static trajectory, in which a quantum system is able to equilibrate at each instant with its environment.
