The probability distribution of the entropy production for the effusion of an ideal gas between two compartments is calculated explicitly. The fluctuation theorem is verified. The analytic results are in good agreement with numerical data from hard disk molecular dynamics simulations.
We elucidate the connection between various fluctuation theorems by a microcanonical version of the Crooks relation. We derive the microscopically exact expression for the work distribution in an idealized Joule experiment, namely, for a convex object moving at constant speed through an ideal gas. Analytic results are compared with molecular dynamics simulations of a hard disk gas.
We discuss the fundamental physical differences and the mathematical interconnections of counterintuitive transport and response properties in Brownian motion far from equilibrium. After reviewing the ubiquity of such effects in physical and other systems, we illustrate the general properties on paradigmatic models for both individually and collectively acting Brownian particles.
We calculate analytically the gain for the N-player primary Parrondo paradox and identify the optimal strategy.
An example of Brownian motion with absolute negative mobility is given and analytically studied in a random walk and diffusion model.
We present the exact analytic solution for the model of directed transport induced by nonequilibrium state occupation, introduced by Porto [Eur. Phys. J. B 25, 345 (2002)].
We introduce simple non-Markovian modifications to the standard random walk resulting in absolute negative mobility, i.e., the response to an external force is always opposite to the direction of the force.
