Distribution of Microscopic Energy Flux in Equilibrium State
arXiv:cond-mat/0702631 · doi:10.1143/JPSJ.76.075001
Abstract
The distribution function P(j) of the microscopic energy flux, j, in equilibrium state is studied. It is observed that P(j) has a broad peak in small j regime and a stretched-exponential decay for large j. The peak structure originates in a potential advection term and energy transfer term between the particles. The stretched exponential tail comes from the momentum energy advection term.
