Fluctuation and dissipation within a deformed holographic model with backreaction

نویسندگان

چکیده

In this work we study the fluctuation and dissipation of a string attached to brane in deformed backreacted AdS-Schwarzschild spacetime. This space is solution Einstein-dilaton equations contains conformal exponential factor exp?(k/r2) metric. We consider backreaction contributions coming only from warp on black hole, where are probe approximation. Within Lorentz invariant holographic model have computed admittance, diffusion coefficient, two-point functions regularized mean square displacement sreg2. From quantity obtain diffuse ballistic regimes characteristic Brownian motion. also checked well know fluctuation-dissipation theorem set up.

Fluctuation 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.

Fluctuation and dissipation

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 theorem and quantum tunneling with dissipation

We suggest to take the fluctuation-dissipation theorem of Callen and Welton as a basis to study quantum dissipative phenomena ( such as macroscopic quantum tunneling ) in a manner analogous to the Nambu-Goldstone theorem for spontaneous symmetry breakdown. It is shown that the essential physical contents of the Caldeira-Leggett model such as the suppression of quantum coherence by Ohmic dissipa...

Test Model for Fluctuation-Dissipation Theorems with Time Periodic Statistics

The recently developed time-periodic fluctuation-dissipation theorem (FDT) provides a very convenient way of addressing the climate change of atmospheric systems with seasonal cycle by utilizing statistics of the present climate. A triad nonlinear stochastic model with exactly solvable first and second order statistics is introduced here as an unambiguous test model for FDT in a timeperiodic se...

The fluctuation-dissipation theorem

The linear response theory has given a general proof of the fluctuationdissipation theorem which states that the linear response of a given system to an external perturbation is expressed in terms of fluctuation properties of the system in thermal equilibrium. This theorem may be represented by a stochastic equation describing the fluctuation, which is a generalization of the familiar Langevin ...
