Quantum Measurement and Entropy Production [PDF]

Physics Letters A, 2000
We study the time evolution of a quantum system without classical counterpart, undergoing a process of entropy increase due to the environment influence.

Entropy production by resonance decays [PDF]

Physical Review C, 1996
We investigate entropy production for an expanding system of particles and resonances with isospin symmetry -- in our case pions and $\rho$ mesons -- within the framework of relativistic kinetic theory. A cascade code to simulate the kinetic equations is

Entropy Production in the Theory of Heat Conduction in Solids [PDF]

Entropy, 2016
The evolution of the entropy production in solids due to heat transfer is usually associated with the Prigogine’s minimum entropy production principle.

Entropy Production in Relativistic Hydrodynamics [PDF]

Physics Letters B, 2001
The entropy production occurring in relativistic hydrodynamical systems such as the quark-gluon plasma (QGP) formed in high-energy nuclear collisions is explored. We study mechanisms which change the composition of the fluid, i.e. particle production and/

Entropy Production of Run-and-Tumble Particles [PDF]

Entropy
We analyze the entropy production in run-and-tumble models. After presenting the general formalism in the framework of the Fokker–Planck equations in one space dimension, we derive some known exact results in simple physical situations (free run-and ...

Fluctuation Theorem for Hidden Entropy Production [PDF]

, 2012
In the general process of eliminating dynamic variables in Markovian models, there exists a difference in the irreversible entropy production between the original and reduced dynamics. We call this difference the hidden entropy production, since it is an

Equivalent definitions of the quantum nonadiabatic entropy production [PDF]

, 2014
The nonadiabatic entropy production is a useful tool for the thermodynamic analysis of continuously dissipating, nonequilibrium steady states. For open quantum systems, two seemingly distinct definitions for the nonadiabatic entropy production have ...

Cavitation Characteristics and Structure Optimization of Two-Dimensional Valve Based on Entropy Production Theory [PDF]

Journal of Applied Fluid Mechanics, 2023
In addition to noise and vibration, cavitation also lowers the efficiency, performance, and working lives of two-dimensional valves. To study the effect of cavitation on the flow characteristics of two-dimensional valves, standard  turbulence model and ...

Analysis of flow loss characteristics of slanted axial-flow pump device based on entropy production theory

Royal Society Open Science, 2022
Slanted axial-flow pump devices are widely applied in urban water supply, irrigation and drainage engineering fields. The second law of thermodynamics is applied to investigate the flow loss characteristics of the 30° slanted axial-flow pump model ...
