Strain correlation functions in isotropic elastic bodies: Large wavelength limit for two-dimensional systems
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Strain correlation functions in two-dimensional isotropic elastic bodies are shown both theoretically (using the general structure of isotropic tensor fields) and numerically (usin…
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…
Intramolecular Form Factor in Dense Polymer Systems: Systematic Deviations from the Debye formula
P. Beckrich, A. Johner, A. N. Semenov +3
We discuss theoretically and numerically the intramolecular form factor in dense polymer systems. Following Flory's ideality hypothesis, chains in the melt adopt Gaussian co…
Why polymer chains in a melt are not random walks
J. P. Wittmer, P. Beckrich, J. Johner +4
A cornerstone of modern polymer physics is the `Flory ideality hypothesis' which states that a chain in a polymer melt adopts `ideal' random-walk-like conformations. Here we revisi…
Long Range Bond-Bond Correlations in Dense Polymer Solutions
J. P. Wittmer, H. Meyer, J. Baschnagel +5
The scaling of the bond-bond correlation function along linear polymer chains is investigated with respect to the curvilinear distance, , along the flexible chain and the…
