Measurement of Stochastic Entropy Production [PDF]
Physical Review Letters, 2006 Using fluorescence spectroscopy we directly measure entropy production of a single two-level system realized experimentally as an optically driven defect center in diamond.

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 of Run-and-Tumble Particles [PDF]
EntropyWe 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 ...

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 ...

Characteristics of Cavitation Flow for a Regulating Valve Based on Entropy Production Theory
Energies, 2022 A regulating valve is a key control element in the coal liquefaction industry, whose flow field distribution is related to the entropy production. In order to make a quantitative evaluation of the energy loss in the cavitation flow and calculate the ...

Wigner Entropy Production Rate [PDF]
Physical Review Letters, 2017 The characterization of irreversibility in general quantum processes is an open problem of increasing technological relevance. Yet, the tools currently available to this aim are mostly limited to the assessment of dynamics induced by equilibrium environments, a situation that often does not match the reality of experiments at the microscopic and ...
