Simple models for strictly non-ergodic stochastic processes of macroscopic systems
G. George, L. Klochko, A. N. Semenov +2
We investigate simple models for strictly non-ergodic stochastic processes ( being the discrete time step) focusing on the expectation value and the standard deviation…

Fluctuations of non-ergodic stochastic processes
G. George, L. Klochko, A. N. Semenov +2
We investigate the standard deviation $δv(\tsamp)$ of the variance $v[\xbf]$ of time series $\xbf$ measured over a finite sampling time $\tsamp$ focusing on non-ergodic systems whe…

Ensemble fluctuations matter for variances of macroscopic variables
G. George, L. Klochko, A. N. Semenov +2
Extending recent work on stress fluctuations in complex fluids and amorphous solids we describe in general terms the ensemble average and the standard deviation of…
