Numerical determination of shear stress relaxation modulus of polymer glasses
I. Kriuchevskyi, J. P. Wittmer, O. Benzerara +2
Focusing on simulated polymer glasses well below the glass transition, we confirm the validity and the efficiency of the recently proposed simple-average expression $G(t) = μ_A - h…
Marginally compact hyperbranched polymer trees
M. Dolgushev, J. P. Wittmer, A. Johner +3
Assuming Gaussian chain statistics along the chain contour, we generate by means of a proper fractal generator hyperbranched polymer trees which are marginally compact. Static and…
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 modulus and shear-stress fluctuations in polymer glasses
I. Kriuchevskyi, J. P. Wittmer, H. Meyer +1
Using molecular dynamics simulation of a standard coarse-grained polymer glass model we investigate by means of the stress-fluctuation formalism the shear modulus as a function…
New conserved structural fields for supercooled liquids
Jean Farago, Alexander N. Semenov, Stefan Frey +1
By considering Voronoi tessellations of the configurations of a fluid, we propose two new conserved fields, which provide structural information not fully accounted for by the usua…
