Weak ergodicity breaking in an anomalous diffusion process of mixed origins
arXiv:1311.3061 · doi:10.1103/PhysRevE.89.012136
Abstract
The ergodicity breaking parameter is a measure for the heterogeneity among different trajectories of one ensemble. In this report this parameter is calculated for fractional Brownian motion with a random change of time scale, often called "subordination". We proceed to show that this quantity is the same as the known CTRW case.
8 pages, 3 figures, submitted to Phys. Rev. E. Introduction and appendix have been rewritten in order to increase readability. A third figure was added for illustration of the calculation in the appendix
