Path-dependent entropy production [PDF]
Journal of the Korean Physical Society, 2015 A rigorous derivation of nonequilibrium entropy production via the path-integral formalism is presented. Entropy production is defined as the entropy change piled in a heat reservoir as a result of a nonequilibrium thermodynamic process. It is a central quantity by which various forms of the fluctuation theorem are obtained.

Entropy production theorems and some consequences [PDF]
, 2009 The total entropy production fluctuations are studied in some exactly solvable models. For these systems, the detailed fluctuation theorem holds even in the transient state, provided initially the system is prepared in thermal equilibrium.

Entropy Production Via Particle Production [PDF]
, 1995 I critically examine the notion of ``irreversibility,'' and discuss in what sense it applies to the spontaneous creation of particles in external fields. The investigation reveals that particle creation in very strong fields can only be described by a non-Markovian transport theory.

Entropy Production in Gaussian Thermostats [PDF]
Communications in Mathematical Physics, 2006 We show that an arbitrary Anosov Gaussian thermostat on a surface is dissipative unless the external field has a global potential.

Calculation of the Entropy Balance Equation in a Non-equilibrium Reaction-diffusion System
Entropy, 2010 In this article, we discuss the relationships between thermodynamic quantities and the spatial pattern in a reaction-diffusion model based on the reversible Gray-Scott model.

On the validity of entropy production principles for linear electrical circuits
, 2007 We discuss the validity of close-to-equilibrium entropy production principles in the context of linear electrical circuits. Both the minimum and the maximum entropy production principle are understood within dynamical fluctuation theory.

Entropy production in random billiards
Discrete & Continuous Dynamical Systems - A, 2021 We introduce a class of random mechanical systems called random billiards to study the problem of quantifying the irreversibility of nonequilibrium macroscopic systems. In a random billiard model, a point particle evolves by free motion through the interior of a spatial domain, and reflects according to a reflection operator, specified in the model by ...

Physical Review X, 2017 We study the statistics of infima, stopping times, and passage probabilities of entropy production in nonequilibrium steady states, and we show that they are universal. We consider two examples of stopping times: first-passage times of entropy production

Numerical investigation of entropy generation of turbulent flow in twisted tri-lobed tubes
Case Studies in Thermal Engineering, 2023 Twisted tri-lobed tubes have garnered attention due to their exceptional heat transfer efficiency and straightforward fabrication. Existing literature lacks comprehensive assessments of the overall heat transfer performance of twisted tri-lobed tubes ...

Entropy production of cyclic population dynamics
, 2010 Entropy serves as a central observable in equilibrium thermodynamics. However, many biological and ecological systems operate far from thermal equilibrium. Here we show that entropy production can characterize the behavior of such nonequilibrium systems.
