Fluctuation and dissipation

چکیده
We review the transient version of the work and fluctuation theorem. We verify the theorem explicitly by a microscopically exact analytic calculation of the probability distribution for work or entropy production in three physical examples: the Joule experiment, the compression/expansion of a gas and the process of effusion.

Fluctuation dissipation relations in stationary states of interacting Brownian particles under shear.
The fluctuation dissipation theorem is studied close to the glass transition in colloidal suspensions under steady shear. Shear breaks detailed balance in the many-particle Smoluchowski equation and gives response functions in the stationary state which are smaller at long times than estimated from the equilibrium fluctuation dissipation theorem. During the final shear-driven decay, an asymptot...
متن کاملFluctuation Dissipation Relation for a Langevin Model with Multiplicative Noise
A random multiplicative process with additive noise is described by a Langevin equation. We show that the fluctuation-dissipation relation is satisfied in the Langevin model, if the noise strength is not so strong. keywords fluctuation-dissipation theorem, Langevin equation, multiplicative noise, Levy flight.
متن کاملFluctuation-dissipation theorem and quantum tunneling with dissipation at finite temperature
A reformulation of the fluctuation-dissipation theorem of Callen and Welton is presented in such a manner that the basic idea of Feynman-Vernon and Caldeira -Leggett of using an infinite number of oscillators to simulate the dissipative medium is realized manifestly without actually introducing oscillators. If one assumes the existence of a well defined dissipative coefficient R(ω) which little...
متن کاملJa n 20 02 Experimental study of the Fluctuation - Dissipation - Relation during an aging process
The validity of fluctuation dissipation relations in an aging system is studied in a colloidal glass during the transition from a fluid-like to a solid-like state. The evolution of the rheological and electrical properties is analyzed in the range 1Hz − 40Hz. It is found that at the beginning of the transition the fluctuation dissipation relation is strongly violated in electrical measurements....
متن کاملTime Reversibility, Correlation Decay and the Steady State Fluctuation Relation for Dissipation
Steady state fluctuation relations for nonequilibrium systems are under intense investigation because of their important practical implications in nanotechnology and biology. However the precise conditions under which they hold need clarification. Using the dissipation function, which is related to the entropy production of linear irreversible thermodynamics, we show time reversibility, ergodic...
