On the stochastic thermodynamics of reactive systems

De Decker, Yannick - In: Physica A: Statistical Mechanics and its Applications 428 (2015) C, pp. 178-193

We develop a theoretical framework for the stochastic thermodynamics of reactive systems. We show that the transition probabilities per unit time of reactive events must satisfy specific constraints, in order for stochastic approaches to lead to physically meaningful results in the macroscopic...

Flows, currents, and cycles for Markov chains: Large deviation asymptotics

Bertini, Lorenzo; Faggionato, Alessandra; Gabrielli, Davide - In: Stochastic Processes and their Applications 125 (2015) 7, pp. 2786-2819

general version of the Gallavotti–Cohen (GC) symmetry for the current field and show that it implies the so-called fluctuation … theorem for the GC functional. We also analyze the large deviation properties of generalized empirical currents associated to …

Irreversibility and entropy production in transport phenomena, III—Principle of minimum integrated entropy production including nonlinear responses

Suzuki, Masuo - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 2, pp. 314-325

A new variational principle of steady states is found by introducing an integrated type of energy dissipation (or entropy production) instead of instantaneous energy dissipation. This new principle is valid both in linear and nonlinear transport phenomena. Prigogine’s dream has now been...

Experimental test of the Gallavotti–Cohen fluctuation theorem in turbulent flows

Ciliberto, S; Garnier, N; Hernandez, S; Lacpatia, C; … - In: Physica A: Statistical Mechanics and its Applications 340 (2004) 1, pp. 240-250

We test the fluctuation theorem from measurements in turbulent flows. We study the time fluctuations of the force …-rotating disks and the case of a wind tunnel jet. We first study the symmetries implied by the Gallavotti–Cohen fluctuation theorem …

Superstatistical generalization of the work fluctuation theorem

Beck, C.; Cohen, E.G.D. - In: Physica A: Statistical Mechanics and its Applications 344 (2004) 3, pp. 393-402

We derive a generalized version of the work fluctuation theorem for non-equilibrium systems with spatio …-temporal temperature fluctuations. For χ2-distributed inverse temperature, we obtain a generalized fluctuation theorem based on q … decay rate in this generalized fluctuation theorem is much slower than the conventional exponential decay. This implies that …
