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…

Shear-stress fluctuations in free-standing polymer films
G. George, I. Kriuchevskyi, H. Meyer +2
Using molecular dynamics simulation of a polymer glass model we investigate free-standing polymer films focusing on the in-plane shear modulus and the corresponding shear-stres…
