Improvement of Error Correction in Nonequilibrium Information Dynamics

Entropy, 2023
Errors are inevitable in information processing and transfer. While error correction is widely studied in engineering, the underlying physics is not fully understood.

Covariant nonequilibrium thermodynamics from Ito-Langevin dynamics

Physical Review Research, 2022
Using the recently developed covariant Ito-Langevin dynamics, we develop a nonequilibrium thermodynamic theory for small systems coupled to multiplicative noises.

Quantum Thermodynamics: A Nonequilibrium Green's Functions Approach [PDF]

, 2015
We establish the foundations of a nonequilibrium theory of quantum thermodynamics for noninteracting open quantum systems strongly coupled to their reservoirs within the framework of the nonequilibrium Green functions (NEGF). The energy of the system and

Thermodynamic derivation and use of a nonequilibrium canonical ensemble [PDF]

, 2011
A thermodynamic expression for the analog of the canonical ensemble for nonequilibrium systems is described based on a purely information theoretical interpretation of entropy.

On the Problem of Formulating Principles in Nonequilibrium Thermodynamics

Entropy, 2010
In this work, we consider the choice of a system suitable for the formulation of principles in nonequilibrium thermodynamics. It is argued that an isolated system is a much better candidate than a system in contact with a bath. In other words, relaxation

Chemical thermodynamics for growing systems

Physical Review Research, 2022
We consider growing open chemical reaction systems (CRSs), in which autocatalytic chemical reactions are encapsulated in a finite volume and its size can change in conjunction with the reactions.

Contact Geometry of Mesoscopic Thermodynamics and Dynamics

Entropy, 2014
The time evolution during which macroscopic systems reach thermodynamic equilibrium states proceeds as a continuous sequence of contact structure preserving transformations maximizing the entropy.

Thermodynamic substantiation of the direction of nonequilibrium processes in triadconjugations of machine parts based on the principles of maximum and minimum entropy

Проблеми трибології, 2022
The article gives a thermodynamic substantiation of the direction of nonequilibrium processes in tribocouples of machine parts, in tribosystems, based on the principles of maximum and minimum entropy.

Measuring Nonequilibrium Temperature of Forced Oscillators [PDF]

, 2002
The meaning of temperature in nonequilibrium thermodynamics is considered by using a forced harmonic oscillator in a heat bath, where we have two effective temperatures for the position and the momentum, respectively.
