Linear response, dynamical friction and the fluctuation-dissipation theorem in stellar dynamics
We apply linear response theory to a general, inhomogeneous, stationary stellar system, with particular emphasis on dissipative processes analogous to Landau damping. Assuming only that the response is causal, we show that the irreversible work done by an external perturber is described by the anti-Hermitian part of a linear response operator, and damping of collective modes is described by the...

متن کاملA Dynamical Approach to Fractional Brownian Motion
Herein we develop a dynamical foundation for fractional Brownian Motion. A clear relation is established between the asymptotic behaviour of the correlation function and diffusion in a dynamical system. Then, assuming that scaling is applicable, we establish a connection between diffusion (either standard or anomalous) and the dynamical indicator known as the Hurst coefficient. We argue on the ...
متن کاملAccelerated Stokesian dynamics: Brownian motion
A new Stokesian dynamics ~SD! algorithm for Brownian suspensions is presented. The implementation is based on the recently developed accelerated Stokesian dynamics ~ASD! simulation method @Sierou and Brady, J. Fluid Mech. 448, 115 ~2001!# for non-Brownian particles. As in ASD, the many-body long-range hydrodynamic interactions are computed using fast Fourier transforms, and the resistance matri...
متن کاملBrownian motion under annihilation dynamics.
The behavior of a heavy tagged intruder immersed in a bath of particles evolving under ballistic annihilation dynamics is investigated. The Fokker-Planck equation for this system is derived and the peculiarities of the corresponding diffusive behavior are worked out. In the long time limit, the intruder velocity distribution function approaches a Gaussian form, but with a different temperature ...
