Superstatistical Brownian motion | Christian Beck
; | Date: |
10 Aug 2005 | Subject: | Statistical Mechanics; Mesoscopic Systems and Quantum Hall Effect | cond-mat.stat-mech cond-mat.mes-hall | Abstract: | As a main example for the superstatistics approach, we study a Brownian particle moving in a d-dimensional inhomogeneous environment with macroscopic temperature fluctuations. We discuss the average occupation time of the particle in spatial cells with a given temperature. The Fokker-Planck equation for this problem becomes a stochastic partial differential equation. We illustrate our results using experimentally measured time series from hydrodynamic turbulence. | Source: | arXiv, cond-mat/0508263 | Services: | Forum | Review | PDF | Favorites |
